Andre Mallqui Describe the light reactions of photosynthesis and, for both a C3 and a C4 plant, trace the path of a carbon dioxide molecule from the point at which it enters a plant to its incorporation into a glucose molecule. Include leaf anatomy and biochemical pathways in your discussion of each type of plant. The process of light reactions occurs on the thylakoids, within the grana. Light is required for these processes to take place, both cyclic and non-cyclic photophosphorylation/photosystems I and II. H2O is required and used in order to be split. What absorbs the light are the chlorophyll found within the plants, they are the pigment of green. In order for light reaction to occur, the light entering must be of a specific color and wavelength. During the process of light reaction, chlorophyll

Unformatted text preview: e-s are boosted into a higher orbit allowing their energy to be used to create ATP. This energy is also used to create NADPH+ while ADP and NADP are being used. This process is a redox reaction cause oxygen to be released, which comes from molecules of water. Within C3 and C4 plants carbon dioxide enters the stomata by diffusing from intercellular spaced into mesophyll. Dark reaction occurs within the stroma. Energy from ATP is used in this process; Energy from NADP is reused. C3 plants have palisade and spongy mesophyll; C4 plants have functional mesophyll around the bundle sheaths, and they have Kranz anatomy, chloroplasts in bundle sheath cells. C3 plants combine carbon dioxide with RuBP while C$ plants combing carbon dioxide with PEP. C4 plants also use the CAM pathway....
