Question

what is a crab cycle dital expain​

Answer 1

I think that won't be crab cycle.....that would be krebs cycle..

The answer is Krebs cycle also known as the TCA cycle or CAC 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:

Kreb's cycle or citric acid cycle or the tricarboxylic acid cycle is a series of chemical reactions required for cellular respiration.

This cycle which is used by all aerobic organisms is used to release stored energy through the oxidation of acetyl CoA derived from carbohydrates, fats, and proteins into ATP.

So, yeah. The main function of the Krebs cycle is to produce energy, stored and transported as ATP or GTP.

Explanation:

Through Glycolysis pyruvic acid is produced.

Now if this pyruvic acid is handled in the aerobic respiration way, it undergoes oxidative decarboxylation in presence of pyruvic dehydrogenase, which gives us acetyl CoA.

Acetyl CoA through a through series of reactions called Kreb's cycle is broken down to 2 molecules of CO2, three molecules of NADH, one molecule of FADH2 and one molecule of ATP or GTP.

Glucose molecule produces two molecules of acetyl CoA, so there's 2 cycles. Therefore, the products will double. ie., 4CO2, 6 NADH, 2 FADH2 , 2 ATP or GTP.

Now NADH and FADH2, can produce ATP or GTP in a further process of cellular respiration called oxidative phosphorylation.
