explain the krebs cycle with reaction
Answers
Answer:
The reactions which help in converting pyruvic acid to carbon dioxide and water in mitochondria is called Krebs cycle. It is also known as citric acid or tricarboxylic acid cycle (TCA cycle). In the first reaction of citric acid cycle, acetyl CoA combines with the oxaloacetic acid to form citric acid.
Answer:
The Krebs cycle refers to the reactions that aid in the conversion of pyruvic acid to carbon dioxide and water in mitochondria. The citric acid cycle, or tricarboxylic acid cycle, is another name for it (TCA cycle). Acetyl CoA interacts with oxaloacetic acid to create citric acid in the first step of the citric acid cycle.
Explanation:
In the presence of oxygen, Kreb's cycle is a cyclic activity that happens in the mitochondrial matrix.
Step 1: The cycle begins with the formation of citric acid from the condensation of an acetyl group with oxaloacetic acid and water, followed by the release of the CoA molecule. Citrate synthase is the enzyme responsible for this reaction.
Step 2: Isocitrate is formed when citrate is isomerises.
Step 3: After the synthesis of citrate, two decarboxylation stages are performed: first, the creation of a-ketoglutaric acid, and subsequently succinyl-CoA.
Step 4: Succinyl-CoA is oxidised to malic acid, which is then transformed to oxaloacetic acid, completing the cycle.
