Cellular respiration is a biological process in which cells convert sugar, amino acids and fatty acids into energy utilized by the cell. The process plays an essential role in maintaining the biological functions of all living cells. Cellular respiration begins by breaking down sugars known as glucose during a process called glycolysis.

The major steps or processes of cellular respiration: (1) Glycolysis (2) Krebs cycle (3) Oxidative phosphorylation. The process is called cellular respiration because the cell seems to “respire” in a way that it takes in molecular oxygen (as an electron acceptor) and releases carbon dioxide (as an end product).

Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy in the process, as weak so-called "high-energy...

Cellular respiration can be broken down into 4 stages: Essentially, sugar (C6H12O6) is burned, or oxidized, down to CO2 and H2O, releasing energy (ATP) in the process. Why do cells need ATP? ALL cellular work -all the activities of life - requires energy, either from ATP or from related molecules.

Anaerobic Respiration The first step in cellular respiration in all living cells is glycolysis, which can take place without the presence of molecular oxygen.If oxygen is present in the cell, then the cell can subsequently take advantage of aerobic respiration via the TCA cycle to produce much more usable energy in the form of ATP than any anaerobic pathway.

Cellular respiration occurs in both eukaryotic and prokaryotic cells, with most reactions taking place in the cytoplasm of prokaryotes and in the mitochondria of eukaryotes. There are three main stages of cellular respiration: glycolysis, the citric acid cycle, and electron transport/oxidative phosphorylation.
