The key compound of calvincycle is​

Answer 1

Explanation:

CO2

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.

Answer 2

Answer:

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'.
