Question

why does the body use chemical energy? energy stored in chemical bonds is useful for long - term, but not short - term, energy storage. the potential energy stored in chemical bonds can be released to perform work within a cell. chemical energy produces less heat than other forms of energy when used by the body. chemical energy is the only type of energy that can be converted to thermal energy. energy stored in chemical bonds is difficult to convert to other forms of energy.

Explanation:

The body uses chemical energy because the potential energy stored in chemical bonds can be released through biochemical reactions to perform cellular - level work such as muscle contraction, active transport, and synthesis of molecules. Chemical energy is not just for long - term storage as it can also be used for short - term needs. It is not the only energy that can be converted to thermal energy, and it is relatively easy to convert to other forms of energy within the body. Also, there is no evidence that it produces less heat than other forms of energy when used by the body.

Answer:

The potential energy stored in chemical bonds can be released to perform work within a cell.
