Question

For production of one molecule of glucose in Calvin cycle, choose the appropriate number of molecules of $\mathrm{ATP}$ and $\mathrm{NADPH}$ required:

• A. 18 $\mathrm{ATP}$ and 12 $\mathrm{NADPH}$
• B. 9 $\mathrm{ATP}$ and 6 $\mathrm{NADPH}$
• C. 6 $\mathrm{ATP}$ and 6 $\mathrm{NADPH}$
• D. 6 $\mathrm{ATP}$ and 9 $\mathrm{NADPH}$

Answer 1

The correct option is A 18 $\mathrm{ATP}$ and 12 $\mathrm{NADPH}$

18 $\mathrm{ATP}$ and 12 $\mathrm{NADPH}$ molecules are required to generate one molecule of glucose in Calvin cycle.
