I believe that is fermentation.
When living cells break down food molecules, energy is released in the form of ATP (adenosine triphosphate). This process is known as cellular respiration and occurs in the mitochondria of the cell. ATP is the main energy currency of the cell and is used to power various cellular processes.

limiting calorie intake and increasing energy needs
To get energy. Sugars are particularly important fuel molecules. They are oxidized in the food we eat and must be broken down into smaller molecules before our cells can use them.
well, enzymes are proteins that break up food molecules and digestion is when large protein molecules are broken down
enzymes break down food proteins into smaller molecules that can be carried by blood
The chemical reactions that break down food molecules in cells to release energy are called cellular respiration. This process generates ATP (adenosine triphosphate), which is the energy currency for cellular activities.
