Answer:
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells
Explanation:
During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
Cells require chemical energy for three general types of tasks: to drive metabolic reactions that would not occur automatically; to transport needed substances across membranes; and to do mechanical work, such as moving muscles.
Energy produced from food in the human body is used to maintain the body's essential functions (e.g. cell growth and repair, respiration, blood transport) and perform physical tasks including work, exercise and recreational activities.
Cells do not use the energy from oxidation reactions as soon as it is released. Instead, they convert it into small, energy-rich molecules such as ATP and nicotinamide adenine dinucleotide (NADH), which can be used throughout the cell to power metabolism and construct new cellular components
