A metabolic pathway in aerobic organisms in which acetyl- CoA combines with oxaloacetic acid to form citric acid. For this reason, the Krebs cycle is also known as the citric acid cycle. The cycle produces energy in the forms of ATP, NADH, and FADH2.
Metabolic process that creates at least 90% of the energy used to power the entire body. This energy is called ATP and is formed inside tiny power plants called mitochondria within each cell. The Krebs Cycle (a.k.a. ATP, TCA or Citric Acid cycles) formulates the cellular fuel (glucose + oxygen), ignites it so as to create the ATP, and then eliminates the waste products (CO2 + Water).• Main Glossary• Previous Page
A cyclical series of steps in which pyruvate is oxidised through the mediation of several organic acids.
A series of enzymatic reactions in aerobic organisms involving oxidative metabolism of acetyl units, especially during the process of respiration, to provide the main source of cellular energy in the form of ATP.
