Before acetyl CoA can be formed during respiration, pyruvate must be produced from glycolysis, which occurs in the cytoplasm. This pyruvate is then transported into the mitochondria, where it undergoes decarboxylation by the pyruvate dehydrogenase complex. During this process, one carbon atom is removed from pyruvate as carbon dioxide, and the remaining two-carbon fragment is combined with coenzyme A to form acetyl CoA. Additionally, NAD+ is reduced to NADH in this reaction.

What must happen before acetyl can be formed during respiration?
Glycolysis
What must happen before acetyl CoA can be formed?
Before acetyl CoA can be formed, pyruvate, produced from glycolysis, must be transported into the mitochondria. Once inside, it undergoes oxidative decarboxylation by the pyruvate dehydrogenase complex, where it is converted into acetyl CoA, releasing carbon dioxide in the process. Additionally, NAD+ is reduced to NADH during this conversion.
Acetyl-CoA is formed from the breakdown of pyruvate?
Yes, acetyl-CoA is formed from the breakdown of pyruvate through a process known as pyruvate decarboxylation. This reaction occurs in the mitochondria, where pyruvate, derived from glycolysis, is converted into acetyl-CoA by the pyruvate dehydrogenase complex. During this process, one carbon atom is released as carbon dioxide, and NAD+ is reduced to NADH. Acetyl-CoA then enters the citric acid cycle, playing a crucial role in cellular respiration.
What molecule is formed by the combination of oxaloacetate with acetyl CoA in the first step of the Krebs cycle?
citrate
What is a 6 carbon compound formed during the Krebs cycle?
A 6 carbon compound formed during the Krebs cycle is citrate. It is the first product formed in the cycle when acetyl-CoA combines with oxaloacetate.

Glycolysis
What happen before acetyl CoA can be formed during respiration?
Before acetyl CoA can be formed during respiration, glucose is broken down through glycolysis to produce pyruvate. Pyruvate is then converted to acetyl CoA in the mitochondrial matrix by the enzyme pyruvate dehydrogenase complex. This process generates NADH and CO2 as byproducts.
What must happen before acetyl CoA can be formed?
Before acetyl CoA can be formed, pyruvate, produced from glycolysis, must be transported into the mitochondria. Once inside, it undergoes oxidative decarboxylation by the pyruvate dehydrogenase complex, where it is converted into acetyl CoA, releasing carbon dioxide in the process. Additionally, NAD+ is reduced to NADH during this conversion.
What intermediate is formed in prestep?
The intermediate formed in the prestep of a reaction is typically a reactive species that goes on to react with the starting materials to form the final product. This intermediate is often unstable and exists momentarily during the reaction process before converting into the final product.
Acetyl-CoA is formed from the breakdown of pyruvate?
Yes, acetyl-CoA is formed from the breakdown of pyruvate through a process known as pyruvate decarboxylation. This reaction occurs in the mitochondria, where pyruvate, derived from glycolysis, is converted into acetyl-CoA by the pyruvate dehydrogenase complex. During this process, one carbon atom is released as carbon dioxide, and NAD+ is reduced to NADH. Acetyl-CoA then enters the citric acid cycle, playing a crucial role in cellular respiration.
What is the mechanism of synthesis of acetyl glycine from glycine?
Acetyl glycine is synthesized by combining glycine with acetyl-CoA in a reaction catalyzed by the enzyme glycine N-acyltransferase. This enzyme transfers the acetyl group from acetyl-CoA to the amino group of glycine to form acetyl glycine.
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 is the starting substance of the Krebs Cycle?
The starting substance of the Krebs Cycle is acetyl-CoA, which is formed from the breakdown of carbohydrates, fats, and proteins in the form of pyruvate.
What is the product when methyl amine reacts with acetyl chloride?
When methylamine reacts with acetyl chloride, the product formed is N-acetylmethylamine. This reaction involves the substitution of one hydrogen atom of the methylamine molecule with an acetyl group from acetyl chloride.
What molecule is formed by the combination of oxaloacetate with acetyl CoA in the first step of the Krebs cycle?
citrate
Forms when pyruvic acid reacts with the enzyme CoA?
This reaction forms acetyl CoA, which is a crucial molecule in cellular respiration. Acetyl CoA enters the citric acid cycle to generate ATP through oxidative phosphorylation. This process occurs in the mitochondria of eukaryotic cells.
What is a 6 carbon compound formed during the Krebs cycle?
A 6 carbon compound formed during the Krebs cycle is citrate. It is the first product formed in the cycle when acetyl-CoA combines with oxaloacetate.
