What process occurs before the Krebs cycle?
The formation of acetyl-CoA
What is the main function of the Krebs cylce?
The main function of the Krebs cycle is the complete oxidation of glucose to produce ATP. It is also referred to as the citric acid cycle.
What most the Krebs cycle have that glycolysis doesnt require?
pyruvate
What breaks down pyruvate down into carbon dioxide?
Krebs cycle
What goes into the pyruvate cell?
It is changed into Acetyl CoA, which is then used in the citric acid cycle (aka Krebs Cycle).
What stage of cellular respiration pyruvate as a product?
the krebs cycle produces pyruvate as a product to be used by the ATP molecules.
Before entering Krebs Cycle, pyruvate is?
Oxidized
What happens to pyruvate molecules formed glycolysis in the absence of oxygen?
they will enter the Krebs cycle
What is the end result of glycolysis that eventually feeds into the Krebs cycle?
A. Glucose is broken down into two molecules of pyruvate Glucose is broken down into two molecules of pyruvate.
What is the byproduct of glycolysis?
2 molecules of pyruvate acid that is transported to the Krebs Cycle
Before Krebs cycle can proceed pyruvate must be converted into what?
Pyruvate is converted to acetyl-CoA before entering the Krebs cycle.
What are the Products of the Krebs cycle per molecule of pyruvate?
For one molecule of Pyruvate (pyruvic acid) the Krebs cycle produces 2 molecules of carbon dioxide (CO2), 3 molecules of NADH, one molecule of FADH2, and one molecule of ATP.Also, the change from pyruvate to acetyl CoA produces one NADH and one carbon dioxide molecule; CoA is recycled in and out of the cycle.
What process occurs before the Krebs cycle?
The formation of acetyl-CoA
What is a product of aerobic respiration that will enter into and begin the Krebs cycle?
glycolysis yiels 2 pyruvate molecules that will undergo Kreb's cycle
Which of the following is not a requirement for the Krebs Cycle?
Pyruvate
What stage of cellular respiration produces pyruvate as a product?
Pyruvate is produced at the end of glycoysis and converted into Acetyl CoA and then used in tricarboxylic acid (aka Kreb's, citric acid) cycle to ultimately more ATP.
What is the main function of the Krebs cylce?
The main function of the Krebs cycle is the complete oxidation of glucose to produce ATP. It is also referred to as the citric acid cycle.
