Concept explainers

Photosynthesis

Plants have a capacity that we humans can only imagine— the ability to produce food from sunlight. Sure, we can prepare some dishes that we can savor on, but it become possible because of the plants (as they serve as a producers of all the raw materials required). Photosynthesis is the method of assembling carbohydrates with the aid of sunlight.

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. Step 7: Cleavage of the 6-carbon intermediate into two 3-carbon molecules, which are phosphorylated by ATP and reduced by NADPH to form glyceraldehyde-3-phosphate (G3P) Step 8: Conversion of G3P to…
