What enzyme converts pyruvate into acetyl-CoA?
The enzyme that converts pyruvate into acetyl-CoA is pyruvate dehydrogenase. This multienzyme complex is responsible for catalyzing the conversion of pyruvate into acetyl-CoA, which is a key step in the metabolism of carbohydrates to produce energy.
What can not be formed from pyruvate in human beings?
Pyruvate cannot be directly converted into glucose in humans. This is because humans lack the enzyme pyruvate carboxylase needed for this conversion. Instead, pyruvate is normally converted into acetyl-CoA for entry into the citric acid cycle to produce energy.
The breakdown of pyruvic acid occur?
Pyruvic acid breakdown occurs through a process called pyruvate oxidation, which takes place in the mitochondria. During this process, pyruvate is converted into acetyl-CoA, releasing carbon dioxide and producing NADH. Acetyl-CoA then enters the Krebs cycle to generate more ATP.
What substance is a product of glycolysis?
Pyruvic acid
What are the substrates and products of pyruvate oxidation?
The substrate of pyruvate oxidation is pyruvate, a three-carbon molecule derived from glycolysis. The products of pyruvate oxidation are acetyl-CoA, which is a two-carbon molecule, and carbon dioxide. This process occurs in the mitochondria and is a crucial step in the aerobic respiration pathway.
When is acetyl produced?
During pyruvate processing
Where does the breakdown of pyruvate occur?
Cytoplasm
What is the name of the molecule that pyruvated are changed into during pyruvate processing?
Acetyl CoA
What is the name of the molecule that pyruvate are changed into during pyruvated processing?
Acetyl CoA
What is the name of the molecule that pyruvates are changes into during pyruvate processing?
Acetyl CoA
What is the name of the molecule that pyruvates are change into during pyruvate processing?
Acetyl CoA
What is the name of the molecule that pyruvates are changed into during pyruvate processing?
Acetyl CoA
Where is fatty acid found in a cell?
smooth endoplasmic reticula
If a cell is lacking in oxaloacetate, which of the following will occur?
There will be a buildup of pyruvate in the cell
What is the name of the molecule that pyruvates are changed into during pyruvates processing?
Acetyl CoA
What has to be present for Pyruvate to enter the mitochondria?
The mitochondrial membrane has special transporter proteins which are needed to transport pyruvate. This transport also requires ATP.
Where does the synthesis of pyruvate occur during glycolysis?
The synthesis of pyruvate occurs in the cytoplasm of the cell during glycolysis. It is the final step in the glycolytic pathway, where glucose is converted to two molecules of pyruvate.
