Muscles perform what type of energy transformation?

• A. Chemical energy to mechanical energy
• B. Electrical energy to thermal energy
• C. Mechanical energy to chemical energy
• D. Thermal energy to electrical energy

Answer: (A)

Verified step by step guidance

1. Identify the primary function of muscles in the body, which is to facilitate movement by contracting and relaxing.
2. Understand that muscle contraction involves the conversion of energy from one form to another to perform work.
3. Recognize that muscles use ATP (adenosine triphosphate) as a source of energy, which is a form of chemical energy.
4. Learn that during muscle contraction, the chemical energy stored in ATP is converted into mechanical energy, which is used to produce movement.
5. Conclude that the type of energy transformation performed by muscles is from chemical energy to mechanical energy.
