Detailed explanation-1: -6 molecules of carbon dioxide are required, one for each carbon atom in glucose. 6 molecules of oxygen are produced as a by product of water oxidation. Sunlight provides the free energy needed to make the endergonic pathway proceed.

Detailed explanation-2: -Six “turns” of the Calvin cycle use chemical energy from ATP to combine six carbon atoms from six CO2 molecules with 12 “hot hydrogens” from NADPH. The result is one molecule of glucose, C6H12O6.

Detailed explanation-3: -Solution : Six molecules of ‘CO (2)‘ are required to synthesise on emolecule of glucoses each of which undergoes a ‘C (3)‘ cycle Hence, 6 molecules of ‘CO (2)‘ synthesis a glucose molecule after 6 turns of Calvin cycle.
