Question

q3.5. which of the following does not store potential energy that is usable by a cell? atp protons pumped into the intermembrane space nadh co2

Explanation:

ATP is a high - energy molecule that stores and transfers energy in cells. Protons are pumped into the intermembrane space to create a proton - motive force for ATP synthesis during cellular respiration. NADH is an electron carrier that can be used to generate ATP. CO₂ is a waste product of cellular respiration and does not store potential energy in a form usable by the cell.

Answer:

CO₂
