Question

The main purpose of cellular respiration is to

• A. Convert potential energy to kinetic energy
• B. Convert kinetic energy to potential energy
• C. Convert energy in to cell chemical
• D. Convert energy stored in the chemical bonds of glucose to energy that the cell can use

Answer 1

The correct option is D Convert energy stored in the chemical bonds of glucose to energy that the cell can use

• Cellular respiration is the mechanism of breakdown of food materials within the cell to release energy and the trapping of this energy for synthesis of ATP. Therefore, the main purpose is to convert energy stored in the chemical bonds of glucose to energy that the cell can use.

So, the correct option is 'Convert energy stored in the chemical bonds of glucose to energy that the cell can use'.
