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 both fuel, and an electron acceptor which drives the chemical process of turning energy from that fuel into a useable form.
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 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.
- Definition, Process & Equation 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 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 definition is - any of various energy-yielding oxidative reactions in living matter that typically involve transfer of oxygen and production of carbon dioxide and water as end products. How to use cellular respiration in a sentence.
Define cellular respiration. cellular respiration synonyms, cellular respiration pronunciation, cellular respiration translation, English dictionary definition of cellular respiration. n. The series of metabolic processes by which living cells produce energy through the oxidation of organic substances. The process of metabolism in which...
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.

The process by which organisms exchange gases, especially oxygen and carbon dioxide, with the environment. In air-breathing vertebrates, respiration takes place in the lungs. In fish and many invertebrates, respiration takes place through the gills. Respiration in green plants occurs during photosynthesis.
