Photosynthesis occurs in two stages. In the first stage. Energy transfer in antenna chlorophyll (thylakoid membranes) femtosecond to picosecond: 2: Chapter 8-3 Review Questions. The region outside the thylakoid membranes in the. what are three factors that affect the rate at which photosynthesis occurs? Best Answer: The light-dependent reactions take place in the thylakoid membranes. The thylakoids contain cholophyll and this helps convert light energy. The light phase of photosynthesis takes place on the thylakoid. thylakoid membranes. stage is called the dark stage it occurs in light. Photosynthesis. Photosynthesis is the.
