- DRAW a curved arrow mechanism for photosynthesis with the following steps. Step 1: Absorption of sunlight and excitation of chlorophyll molecules Step 2: Transfer of energy to reaction center chlorophylls, which lose an electron and become oxidized. Step 3: Electron transfer from oxidized chlorophylls to an electron acceptor, such as a quinone molecule Step 4: Electron transfer from the quinone molecule to a chain of electron carriers, such as cytochromes, which generate a proton gradient across the thylakoid membrane Step 5: ATP synthesis by ATP synthase using the energy of the proton gradient. Step 6: Transfer of electrons from the electron carriers to the enzyme rubisco, which catalyzes the carboxylation of ribulose bisphosphate (RuBP) with CO2, forming an unstable 6-carbon intermediate.
