Can atp production take place in chloroplasts in the absence of light? why or why not? atp production can proceed as long as there is a hydrogen ion gradient across the thylakoid membrane. chlorophyll antenna complexes must be active for the redox reactions of electron transport to be functional. the energy required for the phosphorylation of adp in chloroplasts can be supplied only by photon absorption. photons are absolutely required for photosynthesis to work.
