The correct option is C Light independent reaction
Ribulose bisphosphate Carboxylase-Oxygenase (RuBisCO) is the key enzyme responsible for photosynthetic carbon assimilation in catalysing the reaction of (light independent reaction) CO2 with ribulose 1,5‐bisphosphate (RuBP) to form two molecules of D‐phosphoglyceric acid (PGA).
Light dependent reactions include light absorption, water splitting, oxygen release, and the formation of ATP and NADPH.
The electron transport system (ETS) are proteins and complexes of molecules embedded in inner mitochondrial membrane that accept energy from carriers in the matrix and store it to a form high energy molecules.
The complete oxidation of glucose to carbon dioxide and water
is carried out by Krebs cycle which is also called as aerobic respiration.
