Metabolism refers to all the chemical reactions in the body, including those that use oxygen and create carbon dioxide. Oxygen and carbon dioxide, therefore, are involved in both respiration and metabolism. Metabolic reactions are sometimes referred to as cellular respiration, which can cause confusion. read more
Cellular respiration is a series of metabolic processes which all living cells use to produce energy in the form of ATP. In cellular respiration, the cell breaks down glucose to produce large amounts of energy in the form of ATP. read more
The energy needs of the cell — of the cell metabolism — is secured by the ATP/ADP cycle: One could say that cellular respiration is related to metabolism as fuel is related to combustion. Metabolism infograph lifted from academic.pgcc.edu, page metabolism. read more
Cellular respiration is also called aerobic respiration because it takes place when oxygen is present. The purpose of cellular respiration is to make usable energy for the cell. Instead of Red Bull or Monster Energy, cellular energy takes the form of a compound called ATP (short for adenosine triphosphate). read more
