The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions that occur in the mitochondria of cells. It produces ATP, a form of energy, and carbon dioxide as a byproduct. The cycle is crucial for the metabolism of carbohydrates, fats, and proteins.
2acetyl-CoA + 2oxaloacetate -> 4CO2 + 6NADH+2FADH2+ 2ATP + 2oxaloacetate

The Krebs cycle occurs in which region of the mitochondrion?
The Krebs cycle occurs in the mitochondrial matrix, which is the innermost compartment of the mitochondrion.
Which one is formed during the Krebs cycle FADH2 or pyruvic acid?
During the Krebs cycle, FADH2 is formed as a result of the conversion of succinate to fumarate. Pyruvic acid is a product of glycolysis, which occurs prior to the Krebs cycle.
Where does the Krebs cycle occur in bacteria?
The Krebs cycle in bacteria occurs in the cytoplasm. Unlike in eukaryotic cells, where it occurs in the mitochondria, bacterial cells do not have mitochondria, so the Krebs cycle takes place in the cytoplasm.
Which produces more energy Krebs cycle or glycolysis?
The Krebs cycle (or citric acid cycle) produces more energy in the form of ATP compared to glycolysis. The Krebs cycle generates 36-38 ATP molecules per glucose molecule, while glycolysis only produces a net gain of 2 ATP molecules.
What is the starting molecule for the Krebs cycle?
The starting molecule for the Krebs cycle is acetyl-CoA, which enters the cycle by combining with oxaloacetate to form citrate.
What year did Hans Krebs discover the Krebs cycle?
Hans Krebs discovered the Krebs cycle, also known as the citric acid cycle, in 1937.
Are Krebs cycle and tricarboxylic acid interchangeable terms?
Yes, Krebs cycle and tricarboxylic acid cycle are interchangeable terms used to describe the same metabolic pathway in the cell that generates energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. It is named after the scientist who discovered it, Sir Hans Krebs.
In the presence of oxygen glycolysis is followed by?
Krebs cycle.
Which compounds involved in the urea cycle are linked to the Krebs cycle?
Fumarate and aspartate are the compounds that are linked between the urea cycle and the Krebs cycle. Fumarate from the Krebs cycle can be converted to arginine in the urea cycle, while aspartate from the urea cycle can be converted to oxaloacetate in the Krebs cycle.
Prefix of Krebs cycle acid?
Krebs
What occurs in the Krebs cycle?
the Krebs cycle, aka citric acid cycle, occurs in the mitochondrial matrix
Where in the cell do the Krebs cycle?
The Krebs, or citric acid cycle, occurs in the mitochondrial matrix.
Why pyruvic acid do not move as it is in the Krebs cycle?
why pyruvic acid do not move as it is in krebs cycle
Is the TCA cycle the same as Krebs Cycle?
Yes, the TCA (tricarboxylic acid) cycle is another name for the Krebs cycle or citric acid cycle. These terms are used interchangeably to describe the same metabolic pathway that occurs in the mitochondria of cells, producing ATP and carbon dioxide as part of aerobic respiration.
What is a sentence using the word the Krebs cycle?
The Krebs cycle is also called the citric acid cycle (CAC).
In the Krebs cycle acetate combines with what 4-carbon compound?
oxaloacetic acid
What are the consumption of glucose in Krebs cycle?
The Krebs cycle runs twice for each molecule of glucose consumed.
