Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which substance from the light-dependent reactions of photosynthesis is a source of energy for the Calvin Cycle?
A
ADP
B
H2O
C
NADPH
D
pyruvic acid
Explanation: 

Detailed explanation-1: -ATP and NADPH produced by the light-dependent reactions of the photosystems are used by the Calvin cycle in the stroma of the chloroplast.

Detailed explanation-2: -NADPH formation. The net effect of these steps is to convert light energy into chemical energy in the form of ATP and NADPH. The ATP and NADPH from the light-dependent reactions are used to make sugars in the next stage of photosynthesis, the Calvin cycle.

Detailed explanation-3: -The light-dependent reactions convert light energy into chemical energy. The goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to produce ATP and NADPH. These two energy-storing molecules are then used in the light-independent reactions.

Detailed explanation-4: -This pathway is known as the Calvin-Benson Cycle. The reactions are catalyzed by soluble enzymes of the chloroplast stroma. The energy sources for the pathway are the NADPH and ATP produced during the light-dependent reactions of photosynthesis.

Detailed explanation-5: -The light reaction is the first stage of the photosynthesis process in which solar energy is converted into chemical energy in the form of ATP and NADPH. The three products of the light reaction of photosynthesis are ATP, NADPH, and O2.
