- pH and in the Chloroplast Proton-Motive Force (Integrates with Chapter 20.) In mitochondria, the membrane potential () contributes relatively more to p (proton-motive force) than does the pH gradient (pH). The reverse is true in chloroplasts. Why do you suppose that the proton-motive force in chloroplasts can depend more on pH than mitochondria can? Why is () less in chloroplasts than in mitochondria?arrow_forwardAs you learned in this chapter, cell membranes arc required for electron transfer phosphorylation. Thylakoid membranes in chloroplasts serve this purpose in photosynthetic eukaryotes. Prokaryotic cells do not have this organelle, but many are photosynthesizers. How do you think they carry out the light-dependent reactions, given that they have no chloroplasts?arrow_forward2. Describe the ATP cycle, how is ATP used and regenerated in a cell? Fully explain how ATP is generated broken down to ADP and then built back to ATP.arrow_forward
