Question

Quizplus · Accepted Answer

The Calvin cycle, which is the pathway for carbon assimilation in photosynthesis, requires 12 molecules of NADPH and 18 molecules of ATP for the synthesis of one molecule of hexose (a six-carbon sugar) from six molecules of CO2. This energy requirement is due to the need for reducing power (provided by NADPH) and energy (provided by ATP) to drive the endergonic reactions of the cycle.
