How does metabolism relate to energy used for muscle contraction?

1. Energy from metabolism is stored, not used

2. Metabolism involves creating energy for digestion only

3. Metabolism is the conversion of mechanical energy into chemical energy

4. Metabolism translates chemical energy from food into mechanical energy for muscle contraction

The correct answer is: Metabolism translates chemical energy from food into mechanical energy for muscle contraction

Metabolism is the chemical process that occurs in the body to convert food into energy. This energy is then used for various bodily functions, including muscle contraction. Option A is incorrect because the energy from metabolism is not stored, but rather used to power bodily processes such as muscle contraction. Option B is also incorrect because metabolism involves creating energy for all bodily functions, not just digestion. Option C is incorrect because metabolism is not the conversion of mechanical energy into chemical energy, but rather the other way around. The correct answer is D because metabolism translates the chemical energy from food into mechanical energy specifically for muscle contraction.
