What is the process of cellular respiration?The process of cellular respiration releases energy. In order to liberate energy from foods and create ATP (adenosine triphosphate), the molecule that transports energy in cells, a metabolic process takes place in the cells of living things.
Organic substances, like glucose, are broken down in a sequence of enzyme processes that release the stored energy, which is then collected in the form of ATP, during cellular respiration.
Since this process takes place in the presence of oxygen, it is also known as aerobic respiration. Living organisms depend on cellular respiration to survive because it helps in the transportation of the energy needed for all of their cellular functions.
