The carbon source for organisms that derive their energy from photosynthesis is ________. This molecule cannot be used by the calvin cycle to produce triose phosphate or RuBP. Tropical plants are often C-4 plants that can carry out photosynthesis at lower concentrations of carbon dioxide than C-3 plants. Photosynthesis is the biochemical pathway which converts the energy of light into the bonds of glucose molecules. In the first step, CO2 is added to a 5-carbon sugar called ribulose 1, aka RuBP This step is catalyzed by the enzyme ribulose bisphosphate carboxylase oxygenase, or rubisco for short. What are the two challenges to photosynthesis efficiency? (1) The transport of two electrons and two protons, by the diffusion of plastoquinone, from the stroma side of P2 to the luen side of the cytochrome complex and (2) the transfer of electrons within the cytochrome complex to a different molecule of plastoquinone, which results in additional protons being picked up from the stroma and subsequently released into the lumen. On land, where does photosynthesis most readily occur? Describe the Photosynthetic electron transport chain. How the buildup of protons in thylakoid membranes occurs: First, oxidation of water releases protons and O2 into the lumen.
