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 occurs as a series of chemical reactions catalyzed by enzymes, the first of which is glycolysis, a series of anaerobic reactions in which glucose (a 6-carbon molecule) is split into two molecules of lactate (a 3-carbon molecule), producing a net gain of two ATP molecules. In a series of aerobic reactions, lactate is ...
Cellular Respiration Definition. Cellular respiration is the process through which cells convert fuel into energy and nutrients. To create ATP and other forms of energy that they can use to power their life functions, cells require fuel and an electron acceptor which drives the chemical process of turning energy from that fuel into a useable form.
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 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...
Together, the processes of photosynthesis and cellular respiration allow life on Earth to gather energy for use in other reactions. Besides the organisms that rely on sulfur near hydrothermal vents, the majority of life on Earth relies on the sugar glucose. Glucose is created by the process of photosynthesis.

Respiration is a metabolic process common to all living things. Here, you will learn the definition, location, processes, and formula for cellular respiration.
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.
