THE CALVIN CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The energy that drives the Calvin cycle is found in
A
ATP and NADPH
B
Glucose and 3-carbon sugars
C
Stomata and cellulose
D
water and carbon dioxide
Explanation: 

Detailed explanation-1: -The energy from sunlight is briefly held in NADPH and ATP, which is needed to drive the formation of sugars such as glucose. And this all happens in the Calvin cycle.

Detailed explanation-2: -The Calvin cycle is not totally independent of light since it relies on ATP and NADH, which are products of the light-dependent reactions. The light-independent reactions of the Calvin cycle can be organized into three basic stages: fixation, reduction, and regeneration.

Detailed explanation-3: -ATP and NADPH use their stored energy to convert the three-carbon compound, 3-PGA, into another three-carbon compound called G3P. This type of reaction is called a reduction reaction, because it involves the gain of electrons. A reduction is the gain of an electron by an atom or molecule.
