Question

The key compound of Calvin cycle is
(a) PGA
(b) PHAL
(c) DHAP
(d) DPGA​

Answer 1

Answer:

PGAl is the answer

Explanation:

Calvin cycle is a biochemical reaction in which CO2 is fixed with the help of ATP and NADPH2 formed in light reaction, to form carbohydrates. The path of carbon during the reaction was studied by Melvin Calvin. Three molecules of additive 6C compound immediately split up by hydrolysis into six molecules of 3C compound called 3-phosphoglyceric acid (3-PGA).  Six molecules of 3_PGA are further phosphorylated by ATP and converted into six molecules of 1,3-diphosphoglyceric acid (1,3-DPGA). By using ATP and NADPH2 formed in the light reaction, CO2 is reduced to form organic food in the form of 3-phosphoglyceraldehyde 3C (PGAL) and further get converted into glucose (6C) which can be utilized directly in plant metabolism or can be stored in the form of starch.

So the correct answer is 'PGAL'.
