Question

which is the primary acceptor of CO2​

Answer 1

A molecule (e.g. ribulose-1,5-diphosphate) that assimilates carbon dioxide from the air into a plant.

These reactions use chemical energy from NADPH and ATP that were produced in the light reactions.

The final product of the Calvin cycle is glucose

IN C₃ PLANTS

• Rubisco is the primary acceptor of CO₂.
• In C₃ cycle, RuBP (Ribulose-1,5-bisphosphate), RuBP is a 5 carbon compound.

IN C₄ PLANTS

• The primary acceptor of carbon dioxide molecule is phosphoenolpyruvic acid which is present in the chloroplast of mesophyll cells.

Answer 2

compound phosphoenol pyruvic acid

The primary acceptor of CO2, is a 3 carbon compound phosphoenol pyruvic acid. Addition of CO2, to any compound is called carboxylation. In C4 cycle, CO2, combines with phosphoenol pyruvic acid to form oxaloacetic acid.
