When a phosphate group is removed from a molecule of ATP, a molecule of ADP is formed. Energy is released, so it can be used to perform cellular work, such as obtaining, transforming, or transporting materials and eliminating wastes. 2. Lipids are macromolecules used by the body for long-term energy storage. Lipids, like sugars, are composed primarily of carbon, hydrogen, and oxygen. They contain high-energy bonds that can be broken by cells to release energy to do cell work. Sugars contain high-energy bonds, but are used by the body for short-term energy storage.
12 3. On the underside of leaves, pairs of guard cells create microscopic pores called stomata. These allow for the exchange of gases between the environment and the interior cells. This gas exchange is vital to plant cell photosynthesis, which requires carbon dioxide gas as a reactant. In addition, excess oxygen created as a product is removed through stomata. 4. Chloroplasts in photosynthetic organisms convert radiant energy from the Sun into condensed carbon compounds such as carbohydrates. The plants then either convert these carbohydrates into structural or storage materials, or use them to generate ATP for cellular processes. 5. The process of cellular respiration can be generally expressed by: glucose + oxygen carbon dioxide + water + ATP So, the reactants in cellular respiration are glucose and oxygen. 6. Chloroplasts are mainly found in plants. In the chloroplasts are stacks of flattened disks that contain proteins that help capture light from the Sun during the process of photosynthesis. 7. The processes of photosynthesis and cellular respiration are interdependent. The products of one process act as the starting materials, or reactants, of the other process. Photosynthesis produces glucose and oxygen. These products are used as reactants in the process of aerobic respiration. Aerobic respiration produces carbon dioxide and water. These products are used as reactants in the process of photosynthesis. 8. Plastids are membrane-bound organelles that can be found in plant and algae cells. In plants, these organelles can differentiate into various forms to play different roles within the cell. A chloroplast is a type of plastid that is involved in the transformation of energy within a cell because this is the organelle in which photosynthesis occurs. Other plastids perform different functions. For example, amyloplasts are used to store starch; chromoplasts are used for pigment synthesis and storage; and elaioplasts store fats within the cell. 9. Photoautotrophs are organisms that can perform photosynthesis, a pathway that converts the energy from sunlight into the chemical energy of organic molecules. These molecules can then store the collected energy for later use when needed. Land plants, algae, and some kinds of bacteria are photoautotrophs, but animals cannot use light energy. They require an input of energy that is already in an organic molecule form (i.e. food). 10. There is a one-way flow of energy from the Sun to all of the organisms in an ecosystem. Energy flows first into the lowest trophic level of an ecosystem via photosynthesis. Carbohydrate products from photosynthesis are then broken down to liberate energy through cellular respiration. Heat is lost to the environment at each step during energy transfer through the ecosystem.
13 11. In chloroplasts, organelles only found in autotrophs, such as plants, algae, and cyanobacteria, carbon dioxide and water are transformed into glucose and oxygen when solar energy excites electrons in chlorophyll. 12. Cells get energy to perform their necessary functions by taking in nutrients from food. During the digestive process, nutrients from food are broken down and used to synthesize sugar, or glucose, molecules. When the glucose is broken down, a lot of energy is created. This energy is then used for various cell functions. 13. When adenosine binds with two phosphate molecules, it is known as adenosine diphosphate (di meaning 2). With three phosphate molecules, it is adenosine triphosphate (tri meaning 3). Cells use ATP (Adenosine TriPhosphate) to temporarily store energy. When the cell is in need of energy, a reaction occurs in which the ATP becomes ADP (Adenosine DiPhosphate) and energy is released. 14. Photosynthetic pigments, which absorb and convert light energy into chemical energy, are embedded in the membranous structure of chloroplasts in plant cells. These pigments give chloroplasts, and plants, their characteristic green color because they absorb all colors of the visible spectrum except green. Once light energy is converted into a chemical form, enzymes present inside chloroplasts can use this energy to synthesize fuel storage molecules like glucose and starch. 15. The process of photosynthesis can be generally expressed by: carbon dioxide + water + light glucose + oxygen So, the reactants in photosynthesis are carbon dioxide and water. 16. The cellular processes of photosynthesis and respiration involve the transformation of matter and energy. Carbon-containing molecules, such as glucose, that are formed as a product of photosynthesis can be used to assemble larger molecules, such as DNA, proteins, and fats. Furthermore, energy that is released when these molecules react with oxygen during cellular respiration can be used to fuel other life processes. 17. During aerobic respiration, glucose is broken down in a cell's mitochondria. The products that result from the breakdown of glucose include carbon dioxide, water, and energy. C 6 H 12 O 6 (glucose) + 6 O 2 (oxygen) 6 CO 2 (carbon dioxide) + 6 H 2 O (water) + ATP (energy)
14 Therefore, aerobic respiration is different from photosynthesis because during aerobic respiration, cells take in O 2 and release CO 2, H 2 O, and ATP. 18. During aerobic respiration, cells use oxygen to release the energy stored in glucose. This energy is temporarily stored in the form of ATP (adenosine triphosphate), and water and carbon dioxide are released as wastes. 19. Mitochondria are often referred to as the main power source of a cell. That is because of mitochondria's ability to break down glucose and other food molecules to produce energy. The energy released by mitochondria is stored in an ATP molecule. Without mitochondria, cells would not be able to generate energy to perform cellular work, and cellular death would be the result. 20. Adenosine triphosphate, or ATP, is a macromolecule used by the body for energy storage. ATP contains adenine, ribose, and three phosphate groups. Each of the phosphate bonds stores a large quantity of energy which is released for use when the bond is broken. When this reaction occurs in reverse, cells perform dehydration reactions to add phosphate groups to ADP and store energy for later use. 21. There is a one-way flow of energy from the Sun to all of the organisms in an ecosystem. Energy flows first into the lowest trophic level of an ecosystem via photosynthesis. Carbohydrate products from photosynthesis are then broken down to liberate energy through cellular respiration. Heat is lost to the environment at each step during energy transfer through the ecosystem. 22. Chloroplasts are mainly found in plants. In the chloroplasts are stacks of flattened disks that contain proteins that help capture light from the Sun during the process of photosynthesis. 23. ATP is a high-energy molecule composed of a purine base (adenine), a five-carbon sugar (ribose), and three phosphate groups. It is primarily used as a source of energy in living organisms. ATP supplies energy to every endergonic reaction that occurs in the body. For example, the energy from ATP can be used by the organism to obtain, transform, and transport materials, and to eliminate wastes. 24. When adenosine binds with two phosphate molecules, it is known as adenosine diphosphate (di meaning 2). With three phosphate molecules, it is adenosine triphosphate (tri meaning 3). Cells use ATP (Adenosine TriPhosphate) to temporarily store energy. When the cell is in need of energy, a reaction occurs in which the ATP becomes ADP (Adenosine DiPhosphate) and energy is released. 25. During metabolism, ATP is broken down to fuel chemical reactions, or it can be created by chemical reactions.
15 Metabolism is often divided into two main categories - catabolism and anabolism. Catabolism is the set of chemical reactions that breaks large molecules into smaller units. During catabolic processes, ATP (energy) is created and released. Anabolism is the set of chemical reactions that builds large molecules from smaller units. During anabolic processes, ATP (energy) is broken down and used for fuel. ATP usually remains in the cell that creates it, so it is not shuttled from cell to cell. 26. The cellular processes of photosynthesis and respiration involve the transformation of matter and energy. According to the law of conservation of energy, energy can neither be created nor destroyed. So, in order to obtain excess energy to fuel cellular processes, the bonds formed in the new compounds must have less energy than the bonds in the original food molecules. 27. Only plants and other photosynthetic organisms, such as phytoplankton, can make sugar molecules using energy from the Sun. However, plant cells and animals cells use the energy stored in the bonds of the sugar molecules to fuel cellular processes. The process in which energy is released from glucose molecules and used to do cellular work is called cellular respiration. In either plant or animal cells, cellular respiration takes place primarily in the mitochondria. 28. Chloroplasts in photosynthetic organisms convert radiant energy from the Sun into condensed carbon compounds such as carbohydrates. The plants then either convert these carbohydrates into structural or storage materials, or use them to generate ATP for cellular processes. 29. Chloroplasts are organelles used by plant cells to make a sugar called glucose from sunlight. Energy stored in the chemical bonds of the sugar molecules can be used, either by the plants or by the animals that eat them, to fuel body processes. Because plants make their own food, they make up the first (and most important) trophic level in the energy pyramids of terrestrial ecosystems. Some microorganisms, called phytoplankton, also have chloroplasts. These organisms form the first trophic level in marine ecosystems. 30. Photosynthesis is the process by which organisms, such as green plants, use light energy to produce food. Cellular respiration is the process by which living things, including both plants and animals, obtain energy from the bonds of food molecules. Therefore, plants use light energy to produce food molecules during photosynthesis, and obtain cellular energy from the bonds of these food molecules during cellular respiration.
