Question

c. endosymbiotic d. chemiosmotic 55. ATP is synthesized in photosynthesis by which of the following means? a. Light energy stored by chlorophyll of photosystem I is directly transferred to ATP synthase, which uses the energy to synthesize ATP b. Light energy absorbed by photosystems I and II generate energetic electrons that cause the cytochrome bý complex to pump protons across the thylakoid membrane, these protons drive ATP synthase to synthesize ATP c. Light energy absorbed by photosystems I and generate energetic electrons that cause the cytochrome bf complex to pump protons across the inner chloroplast membrane; these protons drive ATP synthase to synthesize ATP d. Light energy is used to synthesize glucose, which is then metabolized to produce ATP

Explanation / Answer

55. The answer is b. Light energy absorbed by photosystem I and II generate energetic electrons that cuse the cytochrome bf complex to pump protons across the thylakoid membranel these protons drive ATO synthase to synthesize ATP.
