Question

kred's cycle : Explain​

Answer 1

Answer:

The citric acid cycle – also known as the TCA cycle or the Krebs cycle – is a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins.

Answer 2

Answer:

The Krebs cycle sometimes referred to as the TCA cycle or the citric acid cycle is a series of chemical processes that take place in the mitochondria and are essential for aerobic respiration, the process by which practically all living things generate energy. It consumes oxygen and produces water and carbon dioxide as waste. Here, ATP is created from ADP.

Explanation:

It consists of eight steps.

1) Coenzyme A is released when acetyl CoA condenses with oxaloacetate to create citrate (6C).

2) The change from citrate to its isomer, isocitrate.

3) Isocitrate is converted to -ketoglutarate by dehydrogenation and decarboxylation (5C).

4) Oxidative decarboxylation creates succinyl CoA from -ketoglutarate (5C) (4C).

5) Substrate-level phosphorylation of GDP to produce GTP and the conversion of succinyl CoA to succinate by the succinyl CoA synthase enzyme.

6) Succinate dehydrogenase's oxidation of succinate to fumarate.

7) The addition of one H2O transforms fumarate into malate.

8) Oxaloacetate is created when malate is dehydrogenated. This compound then reacts with an additional acetyl CoA molecule to initiate a new cycle.
