Detailed explanation-1: -The Calvin cycle refers to the light-independent reactions in photosynthesis that take place in three key steps. Although the Calvin Cycle is not directly dependent on light, it is indirectly dependent on light since the necessary energy carriers (ATP and NADPH) are products of light-dependent reactions.

Detailed explanation-2: -Answer and Explanation: The statement that is false concerning the Calvin-Benson cycle is it D. oxidizes carbons.

Detailed explanation-3: -The ATP and NADH are then used by the Calvin cycle to reduce carbon dioxide into sugar molecules. Therefore, without ATP and NADH from the light reactions of photosynthesis, the Calvin cycle cannot occur.

Detailed explanation-4: -The carbon atoms used to build carbohydrate molecules comes from carbon dioxide, the gas that animals exhale with each breath. The Calvin cycle is the term used for the reactions of photosynthesis that use the energy stored by the light-dependent reactions to form glucose and other carbohydrate molecules.

Detailed explanation-5: -The Calvin Cycle All three necessary conditions are required – chlorophyll pigments, the chloroplast “theater, ” and enzyme catalysts. The first stage transforms light energy into chemical energy, stored to this point in molecules of ATP and NADPH.
