THE CALVIN CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is made during the Calvin Cycle?
A
ATP
B
NADPH
C
sugar
D
fat
Explanation: 

Detailed explanation-1: -These reactions use chemical energy from NADPH and ATP that were produced in the light reactions. The final product of the Calvin cycle is glucose.

Detailed explanation-2: -The function of the Calvin cycle is to create three-carbon sugars, which can then be used to build other sugars such as glucose, starch, and cellulose that is used by plants as a structural building material. The Calvin cycle takes molecules of carbon straight out of the air and turns them into plant matter.

Detailed explanation-3: -The Calvin cycle is a progression of reactions that happens in the stoma of chloroplasts in a plant cell. The chemical reactions convert carbon dioxide into glucose with the assistance of ATP and NADPH.

Detailed explanation-4: -So the correct answer is ‘3-PGA’.

Detailed explanation-5: -The immediate products of one turn of the Calvin cycle are 2 glyceraldehyde-3-phosphate (G3P) molecules, 3 ADP, and 2 NADP+. (ADP and NADP+ are not really “products". They are regenerated and later used again in the light-dependent reactions).
