WebThe Calvin cycle (synthesis) uses energy from the light reactions to incorporate CO2 from the atmosphere into sugar. In the light reactions, light energy absorbed by chlorophyll in the thylakoids drives the transfer of electrons and hydrogen from water to NADP+ (nicotinamide adenine dinucleotide phosphate), forming NADPH. WebThe mechanism of photosynthesis in C4 plants was elucidated in the 1960 s by Hatch and Slack in Australia. C4 plants are so-called because the first product of CO2 fixation is a C4 organic acid, oxaloacetate, formed by the carboxylation of phosphoenolpyruvate (PEP) by PEP carboxylase.

WebCarbon fixation in C 4 plants Certain plants—including the important crops sugarcane and corn (maize), as well as other diverse species that are thought to have expanded their geographic ranges into tropical areas—have developed a special mechanism of carbon fixation that largely prevents photorespiration. WebFeb 23, 2024 · In C4 plants, photosynthetic tissues differ structurally and functionally from those in C3 plants. For example, bundle sheath cells in C4 plants are effectively shielded from the atmosphere by a ring of mesophyll cells (Fig. 5.20). This arrangement allows the mesophyll cells to regulate.
