Options:

Answer:

Solution:

In the Calvin cycle, the fixation of one molecule of $C O_{2}$ requires $3$ ATP and $2$ NADPH molecules.

To synthesize one molecule of glucose, $6$ molecules of $C O_{2}$ must be fixed.

Total ATP required = $6 \times 3 = 18$ ATP.

Total NADPH required = $6 \times 2 = 12$ NADPH.

Answer: $18$ ATP and $12$ NADPH
