What are products of the light reactions of photosynthesis that are utilized in the calvin cycle?
Bumek [7]

Answer:

ATP and NADPH

Explanation:

<u>The photosynthesis involves two stages:</u> the light-dependent reactions and the Calvin cycle.

<u>The first stage</u> is called the light-dependent reactions, in which the chlorophylls convert the light energy from the sun into two storage molecule energy, namely ATP (Adenosine triphosphate) and NADPH (energy-carrying molecule). In this stage, the water is converted to oxygen gas.      

<u>The second stage</u> is known as the Calvin cycle, in which the transformation of the carbon from the carbon dioxide into glucose requires the use of ATP and NADPH from the light-dependent reactions.                

Therefore, the products of the light reactions of photosynthesis that are utilized in the Calvin cycle are ATP and NADPH.

I hope it helps you!
