In chloroplasts, the light reactions of photosynthesis involving electron transfer occur in the thylakoid membranes (Figure \(\PageIndex{6}\)). So in glycol icis, you're taking the phosphate groups off the substrate, sticking them onto a teepee, and the energy is from breaking it off its molecule, which is unlike this, where the energy is gained from a proton gradient. Photophosphorylation is the process of utilizing light energy from photosynthesis to convert ADP to ATP. In plants and algae, the pigments are held in a very organized fashion complexes called antenna proteins that help funnel energy, through resonance energy transfer, to the reaction center chlorophylls.
