1 Chapter 6 WHERE IT STARTS PHOTOSYNTHESIS
2 Introduction Before photosynthesis evolved, Earth s atmosphere had little free oxygen Oxygen released during photosynthesis changed the atmosphere Favored evolution of new metabolic pathways, including aerobic respiration
3 Sunlight as an Energy Source Visible light A small part of a spectrum of electromagnetic energy radiating from the sun Travels in waves Wavelength The distance between the crest of two successive waves of the light is called wavelength Measured in nanometer (nm) It is organized as photons or packets of electromagnetic energy
4 Electromagnetic Spectrum
5 Photosynthetic Pigments Photosynthesis begins when photons are absorbed by photosynthetic pigment molecules Pigments absorb nearly all wavelengths of visible light The wavelength of light that are not absorbed are reflected as its characteristic color
6 Major Photosynthetic Pigments Chlorophyll a Main photosynthetic pigment Absorbs violet and red light (appears green) Chlorophyll b, carotenoids, phycobilins Absorb additional wavelengths
7 Overview of Photosynthesis Chloroplasts are organelles of photosynthesis in plants They have three membranes Two enclose a semifluid matrix called stroma Folded thylakoid membrane Chloroplasts contain two kinds of photosystems, type I & type II
8 Sites of Photosynthesis
9 6.3 Overview of Photosynthesis Photosynthesis proceeds in two stages Light-dependent reactions Light-independent independent reactions 6H 2 O + 6CO 2 Summary equation: Light energy enzymes 6O 2 + C 6 H O 6
10 Sites of Photosynthesis: Chloroplasts Light-dependent reactions occur at a much-folded thylakoid membrane Forms a single, continuous compartment inside the stroma (chloroplast s s semifluid interior) Light-independent independent reactions occur in the stroma
11 Products of Light-Dependent and Light Independent Reactions Light - Dependent Typically, sunlight energy drives the formation of ATP and NADPH Oxygen is released from the chloroplast (and the cell) Light Independent Synthesis of sugar and other carbohydrates
12 sunlight O 2 H2O CO2 CHLOROPLAST lightdependent reactions NADPH, ATP NADP+, ADP sugars lightindependent reactions CYTOPLASM In chloroplasts, ATP and NADPH form in the light-dependent stage of photosynthesis, which occurs at the thylakoid membrane. The second stage, which produces sugars and other carbohydrates, proceeds in the stroma.
13 Light-Dependent Reactions Two types of photosystems In thylakoid membrane Light-harvesting harvesting complexes Absorb light energy and pass it to photosystems which then release electrons Photosynthesis begins when photon energy is captured by light harvesting complexes and transferred to photosystem II P700 Photosystem I, absorb energy of 700nm P680 Photosystem II, absorb energy of 680nm
14 Noncyclic Photophosphorylation Electrons released from photosystem II flow through an electron transfer chain At end of chain, they enter photosystem I Photon energy causes photosystem I to release electrons, which end up in NADPH Photosystem II replaces lost electrons by pulling them from water Photolysis The process by which the energy of light breaks down a molecule
15 ATP Formation In both pathways, electron flow through electron transfer chains causes H + to accumulate in the thylakoid compartment A hydrogen ion gradient builds up across the thylakoid membrane H + flows back across the membrane through ATP synthases into stroma The ATP and NADPH formed are used in sugar-synthesizing, synthesizing, light-independent independent reactions in the stroma
16 Noncyclic Photophosphorylation
17 Cyclic Photophosphorylation Electrons released from photosystem I enter an electron transfer chain,, then cycle back to photosystem I It yields only ATP NADPH does not form, oxygen is not released
18 Energy Flow in Light-Dependent Reactions
19 Light Independent Reactions: The Sugar Factory Calvin Benson cycle build sugars in the stroma of chloroplast Light-independent independent reactions proceed in the stroma Carbon fixation: : Enzyme rubisco attaches carbon from CO 2 to RuBP (a 5 carbon molecule) to start the Calvin Benson cycle
20 Calvin Benson Cycle Cyclic pathway makes phosphorylated glucose Uses energy from ATP, carbon and oxygen from CO 2, and hydrogen and electrons from NADPH Reactions use glucose to form photosynthetic products (sucrose, starch, cellulose) Six turns of Calvin Benson cycle fix six carbons required to build a glucose molecule from CO 2
21 Light-Independent Reactions
22 Adaptations: Different Carbon-Fixing Pathways Environments differ Plants have different details of sugar production in light-independent independent reactions On dry days, plants conserve water by closing their stomata Stomata is a small opening across the surface of leaves O 2 from photosynthesis cannot escape
23 Plant Adaptations to Environment C3 Plant At high O 2,rubisco attaches oxygen (not carbon) to RuBP in a pathway called photorespiration This reduces the efficiency of sugar production
24 O 2 CO 2 sugar RuBP Calvin- Benson cycle PGA glycolate ATP NADPH C3 plants. On dry days, stomata close and oxygen accumulates in air spaces inside leaves. The high concentration of oxygen makes rubisco attach oxygen instead of carbon to RuBP. Cells lose carbon and energy as they make sugars.
25 Plant Adaptations to Environment C4 plants Carbon fixation occurs twice First reactions release CO 2 near rubisco, limit photorespiration when stomata are closed
26 CO 2 from inside plant C4 oxaloacetate cycle CO 2 sugar RuBP Calvin- Benson cycle PGA C4 plants. Oxygen also builds up in the air spaces inside the leaves when stomata close. An additional pathway in these plants keeps the CO2 concentration high enough to prevent rubisco from using oxygen.
27 Plant Adaptations to Environment CAM plants (Crassulacean Acid Metabolism) Open stomata and fix carbon at night
