glucose molecules.

Answer 2

macromolecules such as carbohydrates, proteins, and lipids in food. The process of breaking down these macromolecules into simpler molecules such as glucose, amino acids, and fatty acids is called digestion.

During digestion, enzymes break down the macromolecules by breaking the chemical bonds that hold them together. These bonds contain potential energy that is released when they are broken. This energy is then stored in the form of ATP molecules, which cells use for energy during cellular respiration.

So, to answer your question, the chemical energy for respiration is stored in the bonds of macromolecules such as carbohydrates, proteins, and lipids in food.
