Question

What compounds are produced by the krebs cycle for each molecule of acetic acide that enters the cycle?

Answer 1

The citric acid cycle, also known as the tricarboxylic acid cycle (TCA cycle) or the Krebs cycle,  is a series of enzyme-catalysed chemical reactions of central importance in all living cells that use oxygen as part of cellular respiration.

TO ANSWER your question,

I  will include a brief summery of the Krebs cycle with step by step compound formation underneath......

STEPS

1. The citric acid cycle begins with acetyl-CoA transferring its two-carbon acetyl group to the four-carbon acceptor compound (oxaloacetate) to form a six-carbon compound (citrate).

2. The citrate then goes through a series of chemical transformations, losing first one, then a second carboxyl group as CO2. The carbons lost as CO2 originate from what was oxaloacetate, not directly from acetyl-CoA.

3. The carbons donated by acetyl-CoA become part of the oxaloacetate carbon backbone after the first turn of the krebs cycle cycle.

Loss of the acetyl-CoA-donated carbons as CO2 requires several turns of the citric acid cycle. However, because of the role of the citric acid cycle in anabolism, they may not be lost since many TCA cycle (KREBS CYCLE) intermediates are also used as precursors for the biosynthesis of other molecules.

4. Most of the energy made available by the oxidative steps of the cycle is transferred as energy-rich electrons to NAD+, forming NADH. For each acetyl group that enters the Krebs  cycle, three molecules of NADH are produced.

5. Electrons are also transferred to the electron acceptor Q, forming QH2.

At the end of each cycle, the four-carbon oxaloacetate has been regenerated, and the cycle continues.

THE FINAL PRODUCTS of the KREBS CYCLE

Products of the first turn of the cycle are: one GTP (or ATP), three NADH, one QH2, two CO2.

Because two acetyl-CoA molecules are produced from each glucose molecule, two cycles are required per glucose molecule.

http://en.wikipedia.org/wiki/Krebs_cycle

Therefore, at the end of all cycles, the products are:

two GTP,

six NADH,

two QH2, and

four CO2 ( IMPORTANT)
