Lera25 [3.4K]

The constant turnover of body tissues requires the <u>chemical energy </u>supplied by carbohydrates, proteins, and lipids.

<h3> What is Chemical energy?</h3>

  • Exothermic reactions are those in which chemical energy is released during the reaction, frequently in the form of heat.
  • Some of the heat energy needed for a reaction to continue can be stored as chemical energy in newly created bonds.
  • The body transforms the chemical energy in food into heat and mechanical energy.
