Q. Glucose synthesis occurs during which stage of $C_{3}$ cycle?

Photosynthesis in Higher Plants

Solution:

During reduction stage of $C_{3}$ cycle, a series of reactions lead to the formation of glucose. The steps involve utilisation of two molecules of $ATP$ for phosphorylation and two of $NADPH$ for reduction per $CO_{2}$ molecule fixed. The fixation of six molecules of $CO_{2}$ and $6$ turns of the cycle are required for the removal of one molecule of glucose from the pathway.
