Question

CO2 acceptor in the mesophyll cells of a C4 plant is

Answer 1

In C4 plants, the carbon dioxidefixation takes places twice (one inmesophyll cells, second in bundle sheath cells). C4 plants possess twoCO2 acceptors (primary acceptor and secondary acceptor). The atmosphericCO2 acceptor in C3 plants is RuBP (Ribulose-1,5-bisphosphate).
