As 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?

Light Reactions Dark Reactions Sugar Chloroplast Light ATP NADPH Calvin cycle NADP ADP Granum H,O co, Figure 7.3. Processes of photosynthesis. The light reactions directly require light energy from the sun. The "dark reactions" are driven by the high energy electrons produced by the light reactions. Some biologists refer to the two parts of photosynthesis as the light reactions and the synthesis reactions. Which part do you think that they call the light reactions?
