Cellular respiration is the process by which organisms use oxygen to break down molecules to receive chemical energy for cell functions and takes place in the cells of animals, plants, and fungi, and also in algae and other protists however what is being discussed more specifically is aerobic respiration, a catabolic molecule that consume oxygen and organic molecules, producing adenosine triphosphate. The term cellular respiration includes both aerobic and anaerobic respiration but however is commonly used as a synonym to aerobic respiration. Cellular respiration occurs in the mitochondria of most cells and is an important process of life itself. In an abridged explanation, cellular respiration converts organic molecules, and oxygen into energy, water and carbon dioxide. Photosynthesis is the conversion of light energy to chemical energy that is stored in sugers or other organic compounds that occurs in plants, algae, and certain prokaryotes. (Campbell, 2008) Photosynthesis is a similar but drastically different process to cellular respiration, rather being the equivalent aerobic respiration in reverse. (Campbell, 2008) The main difference is that in photosynthesis, glucose is created from the conversion of light, while during respiration, glucose is created from the conversion of oxygen, or oxidation.

The highlight of this is chemiosmosis, a energy-coupling mechanism that uses energy stored in the form of a hydrogen ion gradient across membrane to drive cellular work. This is more commonly referred to as the electron transport train, pumping hydrogen protons across a membrane from a region of low hydrogen concentration to an area of high hydrogen concentration.The protons then
