Question

3. How do we get energy required to do work? How is this energy released in the body?​

Answer 1

Answer:

Energy and Work Energy is the capacity to do work or to produce heat. Internal energy is the sum of kinetic energy and the potential energy. ... The KE would increase because heating something causes an increase in temperature. Since the kinetic energy has increased the internal energy has also increased.

Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. ... When the cell uses oxygen to break down sugar, oxygen is used, carbon dioxide is produced, and energy is released.

Answer 2

Energy is produced during the process of respiration . It is stored in the form of ATP and phosphate bonds in mitochondria . When these phosphate bonds are broken then it releases energy which is used to run several metabolic activities in our body. Each ATP releases 7200 calories of energy
