Which of the following is necessary for the light-independent reactions to proceed?
Yanka [14]

Answer;

C) ATP

Explanation;

-Photosynthesis can be divided into two parts: the light-dependent reactions and the light-independent reactions (also referred to as the "dark" reactions).

-The two products of the light-dependent reactions of photosystem are ATP and NADPH.  The movement of high energy electrons releases the free energy that is needed to produce these molecules.  The ATP and NADPH are used in the light-independent reactions to make sugar.

-The light-independent reactions, or dark reactions, of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a chloroplast outside the thylakoid membranes.
