Question

The form of energy used in the process of respiration is:

• A. Chemical energy
• B. Electrical energy
• C. Mechanical energy
• D. Solar energy

Answer 1

The correct option is A Chemical energy

Chemical energy is stored in the bonds of glucose. During the process of respiration (aerobic respiration), the glucose molecule is broken down to release carbon dioxide, water, and energy. This process releases the energy of glucose which is then stored as energy in ATP molecules. ATP molecules are the 'energy currencies of the cell'.
So, the correct answer is option A.
