How does energy get unlocked from the food we eat ?
There are 5 major nutrients present in food – carbohydrates, proteins, fats, vitamins, and minerals. Energy is present in fats and carbohydrates present in food. Cellular respiration is the process by which the energy of these carbohydrates and fats is unlocked in the body. In this process, food in the presence of oxygen is converted to carbon dioxide, water and the energy stored in the food is released.
