Question

The amount of assimilatory power required to fix three CO2 molecules in a C3 plant is
​

Answer 1

Answer:

For every carbon dioxide molecule that is fixed, 3 ATPs are utilized in C4 plants (2 ATPs in C3 plants). C4 plants undergo both C4 and C3 cycles for the formation of sugars (glucose). Hence, for every glucose molecule that is produced, (3 x 6) + (2 x 6) = 18 + 12 = 30 ATPs are required.
