Introduction to BIOENERGETICS & FREE ENERGY

Energy is required to maintain the structure and function of the living cells. This energy is derived from oxidation of carbohydrates, lipids and protein in diets.

• The energy liberated is converted into ATP, which is known as the energy currency of the living cells. • Each gram of carbohydrate and protein gives about 4 Kcal on oxidation, while each gram of fat gives about 9 Kcal.

Bioenergetics is the part of biochemistry concerned with the energy involved in making and breaking of chemical bonds in the molecules found in biological organisms
