What four carbon compounds are regenerated at the end of the Krebs cycle?
Oxaloacetate
What are the intermediate products of the Kreb cycle?
A cycle has no beginning or end... But if you are referring to the end product that is recombined to form the first product of the cycle, it is oxaloacetate. Oxaloacetate is a 4-carbon compound that binds to the 2-carbon compound, acetyl-CoA, which is derived from the link reaction after glycolysis. After binding to acetyl-CoA and Coenzyme A leaves the compound, the resulting product is a 6-carbon compound, citrate. Citrate is eventually decarboxylated and oxidised to form oxaloacetate once more.
The Kreb cycle starts with what?
The Krebs cycle starts with acetyl CoA, and combines with oxaloacetate to form citrate, a six-carbon molecule. Citrate is further oxidized until oxaloacetate is again reached at the end to restart the Krebs cycle.
What compound enters the Krebs cycle and is made from the last compound?
Acetyl CoA is the compound that enters the Kreb's cycle.
Acetyl-CoA is produced from?
In eukaryotic cells, acetyl CoA is produced in the mitochondria from molecules derived from sugars and fats.
When does the Kerbs cycle begin?
The citric acid cycle (Kerbs cycle) begins with the transfer of a two-carbon acetyl group from acetyl-CoA to the four-carbon acceptor compound (oxaloacetate) to form a six-carbon compound (citrate).
What compound that is derived from glucose actually enters the Krebs cycle?
Acetyl-Coenzyme A (Acetyl-CoA) is the compound the enters the Kreb's cycle and reacts with oxaloacetate. It is dervied from the pyruvate, produced in glycolysis, that has gone through decarboxylation and has conezyme A attached to it.
How are citric acid produced?
A Condensation reaction between oxaloacetate and acetyl CoA by the enzyme citrate synthase
What four carbon compounds are regenerated at the end of the Krebs cycle?
Oxaloacetate
What substance does the citric acid cycle break down?
The citric acid cycles converts citrate (produced from the combination of oxaloacetate and Acetyl Coenzyme A) back into oxaloacetate in a series of steps that will end up yielding 2 ATP, 3 NADH and 1 FADH2 per pyruvate. *4 NADH if you include the NADH produced from the creation of Acetyl Coenzyme A in the link reaction.

What molecule is formed by the combination of oxaloacetate with acetyl CoA in the ο¬rst step of the Krebs cycle?
citrate
The Kreb cycle starts with what?
The Krebs cycle starts with acetyl CoA, and combines with oxaloacetate to form citrate, a six-carbon molecule. Citrate is further oxidized until oxaloacetate is again reached at the end to restart the Krebs cycle.
Can fatty acids be converted to oxaloacetate?
Not directly. Fatty acid β-oxidation results in acetyl CoA, which is then entered to the Citric Acid cycle. The "last" step of the cycle is the formation of oxaloacetate from malate.
In the Krebs cycle what molecules acquires most of the energy that is released by the oxidation of acetyl CoA and how many of these molecules are produced during each turn if the cycle?
Krebs Cycle is also known as the Citric Acid Cycle. 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). 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. The carbons donated by acetyl-CoA become part of the oxaloacetate carbon backbone after the first turn of the citric acid 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 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 citric acid cycle, three molecules of NADH are produced. Electrons are also transferred to the electron acceptor FAD, forming FADH2. At the end of each cycle, the four-carbon oxaloacetate has been regenerated, and the cycle continues
The compound that actually begins the Kreb's cycle is?
Acetyl CoA (acetyl group) is the compound that enters the Kreb Cycle.
What molecules initiate the citric acid cycle by reacting with oxaloacetate?
Oxaloacetate [oxaloacetic acid], under the strict guidance of the enzyme 'citrate synthase', is reacted with the co-enzyme 'Acetyl-CoA' to form the products CoA and citric acid.
