Two carbon molecule that combines with a four carbon molecule already in the citric acid cycle to produce citric acid?
The two-carbon molecule that combines with a four-carbon molecule in the citric acid cycle to produce citric acid is acetyl-CoA. Acetyl-CoA condenses with oxaloacetate (a four-carbon molecule) to form citrate, the first step in the citric acid cycle.
What metabolites enter the citric acid cycle and is formed in part by the removal of a carbon from one molecule of pyruvate?
Acetyl-CoA is the metabolite that enters the citric acid cycle and is formed in part by the removal of a carbon from one molecule of pyruvate through a process called pyruvate decarboxylation.
What intermediary metabolites enters the citric acid cycle and is formed in part by the removal of a carbon CO2 from one molecule of pyruvate?
The intermediary metabolite that enters the citric acid cycle after the removal of a carbon CO2 from pyruvate is acetyl-CoA. This process is catalyzed by the enzyme pyruvate dehydrogenase, and acetyl-CoA is a key molecule that fuels the citric acid cycle by providing the acetyl group for the first step with oxaloacetate.
How many carbons are in citric acid?
Six carbon atoms are there.Its formula is C6H8O7.
In cellular respiration a two carbon molecule combines with a four carbon with four carbon molecules to form citric acid as part of?
In cellular respiration, a two-carbon molecule (acetyl-CoA) combines with a four-carbon molecule (oxaloacetate) to form citric acid in the first step of the citric acid cycle (Krebs cycle). This process occurs in the mitochondria and is essential for the production of ATP through the oxidation of acetyl-CoA.
Two carbon molecule that combines with a four carbon molecule already in the citric acid cycle to produce citric acid?
The two-carbon molecule that combines with a four-carbon molecule in the citric acid cycle to produce citric acid is acetyl-CoA. Acetyl-CoA condenses with oxaloacetate (a four-carbon molecule) to form citrate, the first step in the citric acid cycle.
What is acetyl CoA and what does it combine?
Acetyl CoA is a molecule that is formed from the breakdown of carbohydrates, fats, and proteins. It combines with oxaloacetate in the citric acid cycle to produce citrate, starting the cycle that generates energy in the form of ATP.

How many of the carbons originally present in acetyl CoA continue on to respiration after the Krebs cycle?
Two carbons from acetyl CoA continue on to the Krebs cycle. These two carbons are eventually released as carbon dioxide during respiration, while the remaining two carbons are used to regenerate oxaloacetate to complete the cycle.
How many acetyl CoA molecules may be obtained from oxidation of a 16-carbon fatty acid?
A fatty acid that contains 20 carbons will yield 10 molecules of acetyl-CoA. Acetyl-CoA is also referred to as acetyl coenzyme A.
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).
In cellular respiration a two carbon molecule combines with a four carbon with four carbon molecules to form citric acid as part of?
In cellular respiration, a two-carbon molecule (acetyl-CoA) combines with a four-carbon molecule (oxaloacetate) to form citric acid in the first step of the citric acid cycle (Krebs cycle). This process occurs in the mitochondria and is essential for the production of ATP through the oxidation of acetyl-CoA.
What are the Outputs of the citric acid cycle?
The net inputs for citric acid cycle are Acetyl CoA, NADH, and ADP. The Net outputs for the citric acid cycle are ATP, NAD, and carbon dioxide.
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
Carbon diocide is released during which stages of cellular respiration?
oxidation of pyruvate to acetyl CoA and the citric acid cycle
