Question

cellular respiration: glucose molecules undergo a series of reactions. this process results in the formation of up to 38 molecules of high - energy atp per each molecule of glucose. what is the source of the energy stored in these atp molecules?

1. chemical energy originally stored in the glucose molecule
2. electric current created during the destruction of electrons in the glucose
3. kinetic energy generated by the chemical reactions
4. potential energy from the difference in the concentration gradients of the cell

Explanation:

Cellular respiration breaks down glucose. The energy stored in glucose's chemical bonds is released and used to make ATP. It's not about electric current from electron - destruction, kinetic energy from reactions alone, or just concentration gradient potential energy. The main source is the chemical energy in glucose.

Answer:

Chemical energy originally stored in the glucose molecule
