MUSCLE PHYSIOLOGY

Detailed explanation-1: -"The energy is stored in the chemical bonds. When you break the bonds, you get energy.” As Derek Muller (from Veritasium) notes, this idea of energy stored in the chemical bonds is very wrong. To get a better understanding of energy in chemical bonds, let’s consider a simplified model.

Detailed explanation-2: -Chemical energy is stored in the bonds that connect atoms with other atoms and molecules with other molecules. Because chemical energy is stored, it is a form of potential energy.

Detailed explanation-3: -The answer is that most bonds cannot actually “store” energy as breaking those bonds actually requires an input of energy. However, bonds do exist that, when broken, can actually release an overall amount of energy that can be used to do useful work.

Detailed explanation-4: -CHEMICAL ENERGY is the energy stored in the bonds between atoms and molecules. Food, fuel, and the energy stored in the chemicals inside a battery are examples. NUCLEAR ENERGY is the energy stored in the nucleus of an atom – the energy that holds the nucleus together.

Detailed explanation-5: -When the bond is broken, energy is released. The type of energy that breaks the bonds can be light, heat, or kinetic. When atoms combine, energy is released.
