Question

question 1 of 10 which equation shows how cells use the energy stored in an energy carrier? a. nadph → nadp⁺ + h⁺ b. nadp⁺ + p → atp c. atp → adp + nadph d. adp + h⁺ → atp

Explanation:

Cells use the energy stored in ATP (adenosine - triphosphate). When ATP is hydrolyzed, it breaks down into ADP (adenosine - diphosphate) and a phosphate group, releasing energy. NADPH is involved in redox reactions in photosynthesis and other processes but not the main energy - release equation for general cell energy use. Option B is an incorrect combination, and option D is the reverse of the energy - storage reaction (ATP synthesis). The correct reaction for energy use is the breakdown of ATP.

Answer:

No correct option provided. The correct equation for energy use by cells is ATP → ADP + Pi + energy (where Pi is inorganic phosphate). But among the given options, none is correct.
