Answer:

glucose

Explanation:

Chemical energy is stored in the bonds that hold the molecule together. ADP can be recycled into ATP when more energy becomes available. The energy to make ATP comes from glucose. Cells convert glucose to ATP in a process called cellular respiration.

The chemical energy to produce ATP comes from the BREAKDOWN of carbon-based molecules into smaller molecules.

  • Cellular respiration is a series of metabolic reactions by which eukaryotic cells produce energy in the form of ATP by using the energy stored in the chemical bonds of carbon-based molecules.

  • These reactions are catabolic reactions in which chemical bonds of larger molecules are broken down, thereby releasing energy.

  • These carbon-based molecules are glucose and fats (lipids).

  • Carbohydrates release 4000 calories (cal) per gram when they are burned during cellular respiration.

  • Conversely, fats (lipids) release approximately 9000 cal per gram when they are burned.

In conclusion, the chemical energy to produce ATP comes from the BREAKDOWN of carbon-based molecules into smaller molecules.
