Krebs cycle / Citric acid cycle / TCA Cycle with steps and diagram

Krebs cycle

Krebs cycle Definition The Krebs cycle, also known as the citric acid cycle or TCA cycle is a series of reactions that take place in the mitochondria resulting in oxidation of acetyl CoA to release carbon dioxide and hydrogen atoms that later lead to the formation of water. This cycle is termed the citric acid cycle as the first metabolic intermediate formed in the cycle is citric acid. This cycle is also termed tricarboxylic acid (TCA) because it was then … Read more

TCA Cycle (Citric acid cycle or Krebs cycle)

Krebs cycle

The tricarboxylic acid cycle (TCA cycle), also known as the citric acid cycle or the Krebs cycle, is a major energy-producing pathway in living bodies. Cells obtain ATP from breakdown of glucose in the absence of oxygen as in glycolysis. However, most organisms normally are aerobic and oxidize their organic fuels completely to CO2 and water. Foodstuffs feed into the citric acid cycle as acetyl-CoA and the acetyl-CoA is oxidized to carbon dioxide and water in order to generate energy. … Read more
