How is energy obtained during starvation or hunger?

Answer»
  • Due to starvation or hunger, there is less supply of nutrients and energy to the body. In such condition, the stored carbohydrates in the body also deplete.
  • In such condition, fats and proteins present in the body are utilized.
  • Fats or lipids are converted into fatty acids and proteins are broken down to amino acids.
  • Fatty acids and amino acids both are converted to acetyl-coenzyme-A.
  • Acetyl-coenzyme-A can undergo series of cyclic reactions and oxidised to liberate energy in the form of ATP molecules.
