In C3 cycle all together __________ ATP molecules and ____________ NADPH2 molecules are required for the synthesis of each molecule of glucose from CO₂.

A6,12

B12,18

C12,6

D18,12

Answer:

D. 18,12

Read Explanation:

In the C3 cycle, or Calvin cycle, 18 ATP molecules and 12 NADPH molecules are required to synthesize one molecule of glucose from carbon dioxide (CO2): One turn: 3 ATP molecules and 2 NADPH molecules are required Six cycles: 3 x 6 = 18 ATP molecules and 2 x 6 = 12 NADPH molecules are required
