Which of these equations best summarizes photosynthesis? A. C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + Energy B. C6H12O6 + 6 O2 → 6 CO2 + 12 H2O C. 6 CO2 + 6 H2O → C6H12O6 + 6 O2 D. 6 CO2 + 6 O2 → C6H12O6 + 6 H2O E. H2O → 2 H+ + 1/2 O2 + 2e C. 6 CO2 + 6 H2O → C6H12O6 + 6 O2 Where does the Calcin cycle occur? It occurs in the Stroma The light reactions of photosynthesis use _____ and produce _____. water ... NADPH Which term describes ATP production resulting from the capture of light energy by chlorophyll? Photophosphorylation **The excitation of chlorophyll by light energy initiates a chain of events that leads to ATP production. True or false? The chemiosmotic hypothesis states that the synthesis of ATP generates a proton gradient that leads to electron flow through an electron transport chain. False **The chemiosmotic hypothesis states that the flow of electrons through an electron transport chain generates a proton gradient that leads to the synthesis of ATP According to the chemiosmotic hypothesis, what provides the energy that directly drives ATP synthesis? Proton gradient **A proton gradient across chloroplast and mitochondrial membranes drives ATP synthesis by the enzyme ATP synthase Which of the following particles can pass through the ATP synthase channel? Protons True or false? The region of ATP synthase that catalyzes the production of ATP from ADP and inorganic phosphate spans the chloroplast membrane. false
