What else can I help you with?
Is the product of glycolysis that enters the Krebs cycle?
Fats and proteins are brought into the Krebs cycle by being converted. They can either be converted to glucose or acetyl which will go through Krebs cycle.
Where do the reactants for the Krebs cycle come from?
The reactants for the Krebs cycle come from the breakdown of carbohydrates, fats, and proteins into acetyl-CoA, which is then used as the starting molecule for the cycle. These molecules are broken down by various metabolic pathways in the cell to produce the necessary substrates for the Krebs cycle.
How is the breakdown of pyruvic acid related to the citirc acid cycle?
It is the carboxylate ion of pyruvic acid, called pyruvate (3C), which passes into the mitochondrial matrix; it loses 1 carbon (as CO2) in the link reaction, & the remaining 2C product enters the citric acid cycle for final breakdown of the carbon chain.
What are the 3 major steps in respiration?
Aerobic Respiration Occurs in 3 Major StagesGlycolysis - breaks glucose down into 2 molecules of pyruvic acid (a 3-C cmpd). This occurs in the cytoplasmKrebs Cycle (Citric Acid Cycle) - breaks pyruvic acid down into CO2. Occurs in mitochondria - O2 requiredElectron Transport System - transfers e that were removed from Krebs intermediates - Occurs in mitochondria and O2 is used
Krebs cycle and glycolysis?
Glycolysis is the process where one molecule of glucose is broken in half, producing two molecules of pyruvic acid. Krebs Cycle (aka Citric acid cycle) is the first set of reactions in respiration.
Can pyruvic acid use in the Krebs cycle?
The pyruvic acid that is produced by glycolysis is used as the initial input for the Krebs Cycle (also called citric acid cycle). In the initial step of the Krebs Cycle, the pyruvic acid is converted to acetyl-CoA via pyruvate decarboxylation. This continues a series of chemical reactions leading to the production of 2 ATP molecules.
What does the Krebs make?
During the Krebs cycle, pyruvic acid from glycolysis is used to make carbon dioxide, NADH, ATP, and FADH2.
What does kreb cycle make?
During the Krebs cycle, pyruvic acid from glycolysis is used to make carbon dioxide, NADH, ATP, and FADH2.
The pyruvic acid that accumulates as a result of glycolysis can be converted to?
The pyruvic acid that accumulates as a result of glycolysis can be converted to acetyl-CoA through the process of pyruvate decarboxylation. Acetyl-CoA can then enter the citric acid cycle to generate ATP through oxidative phosphorylation.

How is glycolosis different from the breakdown of pyruvic acid?
Glycolysis is the breakdown of glucose to give pyruvic acid and energy. Pyruvic acid is then used for different reactions, the most important one being Kreb's cycle.
What molecule moves into the Krebs cycle?
Pyruvate -> Acetyl CoA -> Citrate which is used by the Krebs or Citric Acid Cycle.

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.
