Question:medium

How many ATPs are required in \(C_3\) and \(C_4\) plants respectively for net production of 12 G3P molecules (PGAL entering cytosol) during dark reaction?

Show Hint

Remember: For one glucose molecule \(C_3\) pathway requires \(18ATP\). \(C_4\) pathway requires \(30ATP\). Since one glucose = two G3P molecules, 12 G3P corresponds to six glucose equivalents.
