Detailed explanation-1: -Final answer: The first acceptor of CO2 in the C4 plant is Phosphoenol pyruvate.
Detailed explanation-2: -Phosphoenolpyruvate (PEP) is the 3-Carbon compound and acts as the primary CO2 acceptor in the mesophyll cells of C4 plants, leading to the formation of OAA (Oxaloacetic acid), C4 acid. The enzyme PEP carboxylase or PEPcase catalyses this reaction.
Detailed explanation-3: -PEP (phosphoenol pyruvate) is the CO2 acceptor in C4 plants.
Detailed explanation-4: -The primary CO2 acceptor of C3 plants is Ribulose 1, 5-1bisphosphate (RuBP) and the primary acceptor of CO2 in C4 plants is phosphoenolpyruvate (PEP). Was this answer helpful?
Detailed explanation-5: -RuBP, the first acceptor of carbon dioxide, is a 5 carbon ketose sugar with the chemical formula C5H12O11P2.
