Some statements regarding C2, C3, C4 and CAM plants

a.) For Sucrose synthesis after C2 C3 and C4 cycle having different procedure

b.) C4  cycle reduces occurrence of C2 which is thermodynamically very expensive and toxic by increasing the assimilation of CO2 at high temperature almost at 35⁰ C

c.) C4 plant is generally found in near to equator  and they are more abundant than C3 plant

d.) In Dark when stomata are closed and CO2 not assimilated in the CAM plants
