Question

Per one Calvin cycle, the number of CO$_2$ molecules fixed, ATP utilized, and the number of Glucose, NADPH molecules produced respectively are:

• A. $6; 18; 1; 12$
• B. $6; 12; 1; 18$
• C. $6; 1; 12; 18$
• D. $12; 1; 6; 18$

Hint:

The Calvin cycle is the light-independent reaction of photosynthesis, occurring in the stroma of chloroplasts, using ATP and NADPH to fix carbon into glucose.

Answer 1

The Correct Option is A

Step 1: Understanding the Calvin Cycle
- The Calvin cycle fixes 6 CO$_2$ molecules to synthesize 1 molecule of glucose. - The process consumes 18 ATP molecules and 12 NADPH molecules per glucose molecule produced.
