Cellular respiration
Cellular respiration
A cell releases energy from food in the process of cellular respiration which is in the presence of oxygen, or fermentation which is in the absence of oxygen.
it breaks down food and releases energy
The process that breaks down food molecules and releases energy is called cellular respiration. This process occurs in the cells of organisms and produces ATP (adenosine triphosphate), the energy currency of the cell, through the breakdown of glucose and other molecules in the presence of oxygen.

Mitochondria are the cellular organelles responsible for releasing the energy contained in food through the process of cellular respiration. This process generates ATP, which is the main form of cellular energy used by the cell for various functions.
When a cell releases energy from food without using oxygen, it undergoes a process called anaerobic respiration, specifically fermentation. This process results in a much lower yield of energy compared to aerobic respiration. The byproducts of fermentation can include lactic acid or alcohol, depending on the organism carrying out the process.
