How many additional ATP and molecules are required during synthesis of one glucose molecule in sugarcane than rice plant?
View answer and explanation
Correct option: D
12,0
Option D (12,0) is correct because C4 plants require 2 additional ATP per CO2 fixed compared to C3 plants. For one glucose molecule (6 CO2), this amounts to 12 additional ATP. No additional NADPH2 is required.
