Detailed explanation-1: -The Calvin cycle has four main steps: carbon fixation, reduction phase, carbohydrate formation, and regeneration phase.
Detailed explanation-2: -So, the correct answer is ‘Carboxylation → reduction →Regeneration.
Detailed explanation-3: -(1) Reduction, during which carbohydrate is formed at the expense of the photochemically made ATP and NADPH. (2) Regeneration, during which the carbon dioxide acceptor ribulose-1, 5-biphosphate is formed.
Detailed explanation-4: -Carbon Fixation. Also known as the carboxylation phase, the first step in the Calvin cycle comprises only one irreversible reaction catalyzed by the enzyme ribulose-1, 5-bisphosphate carboxylase/oxygenase (RubisCO). Reduction Phase. Regeneration Phase. 30-Apr-2022
