Question

How many number of $\mathrm{CO}_{2}$ molecules are required to synthesise one molecule of glucose during $\mathrm{C}_{3}$ cycle?\

Professor PC Thomas Classes · Answer

(c) : Six molecules of $\mathrm{CO}_{2}$ are required to synthesise one molecule of glucose, each of which undergoes a $\mathrm{C}_{3}$ cycle. Hence, 6 molecules of $\mathrm{CO}_{2}$ synthesise a glucose molecule after 6 turns of Calvin cycle.\
