Detailed explanation-1: -The chemical energy in the food gets changed into the mechanical energy of moving muscles.
Detailed explanation-2: -Energy transformations occur during the digestive process. When food is broken down, the body transfers energy from chemical energy to thermal and mechanical energy. Chemical energy is potential energy stored in the food we eat. The human body uses thermal energy to maintain body temperature.
Detailed explanation-3: -The human body can be considered an energy conversion device. Humans take in chemical energy in the form of food and convert it to kinetic energy, heat, and other forms of energy. Some components of the human body are also energy conversion devices. Muscles convert chemical energy to kinetic energy.
Detailed explanation-4: -The chemical energy stored in food is released by cells through the process of respiration. This process has four steps, and mainly produces ATP as the energy-carrying molecule that can be used by cells in their metabolic activities.
