What else can I help you with?
What molecule is the common branch point for either the anaerobic or aerobic pathway?
The molecule that serves as the common branch point for either the anaerobic or aerobic pathway is pyruvate. Depending on the availability of oxygen, pyruvate can either be converted into acetyl-CoA to enter the aerobic pathway (Krebs cycle or citric acid cycle) or undergo fermentation in the absence of oxygen.
What most the Krebs cycle have that glycolysis doesnt require?
pyruvate
How does galactose enter the Krebs cycle?
Galactose is converted to glucose-6-phosphate, which can enter glycolysis to produce pyruvate. Pyruvate can then be converted to acetyl-CoA, a molecule that enters the Krebs cycle. This allows galactose-derived metabolites to be utilized in the Krebs cycle for energy production.
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 process occurs before the Krebs cycle?
The formation of acetyl-CoA
Which of the following is not a requirement for the Krebs Cycle?
Pyruvate
At the end of glycolysis whats is transported to the mitochondria to serve as a starting point for the Krebs cycle?
Pyruvate is transported to the mitochondria to serve as a starting point for the Krebs cycle. Once in the mitochondria, pyruvate is converted into acetyl-CoA, which then enters the Krebs cycle to be oxidized for energy production.
What molecule is the common branch point for either the anaerobic or aerobic pathway?
The molecule that serves as the common branch point for either the anaerobic or aerobic pathway is pyruvate. Depending on the availability of oxygen, pyruvate can either be converted into acetyl-CoA to enter the aerobic pathway (Krebs cycle or citric acid cycle) or undergo fermentation in the absence of oxygen.
The Krebs cycle is an example of which type of metabolic pathway?
The Krebs cycle is an example of an aerobic metabolic pathway, as it requires oxygen to function efficiently.
Before entering Krebs Cycle, pyruvate is?
Oxidized
What molecule moves into the Krebs cycle?
Pyruvate -> Acetyl CoA -> Citrate which is used by the Krebs or Citric Acid Cycle.
Before Krebs cycle can proceed pyruvate must be converted into what?
Before the Krebs cycle can proceed, pyruvate must be converted into acetyl-CoA through a process known as pyruvate decarboxylation. This reaction occurs in the mitochondria and is catalyzed by the enzyme pyruvate dehydrogenase complex. Acetyl-CoA then enters the Krebs cycle to be further metabolized for energy production.
What most the Krebs cycle have that glycolysis doesnt require?
pyruvate
What is the substance that enters the Krebs cycle from glycolysis?
In Glycolysis, the final compound formed is Pyruvate. Now, pyruvate has to be transformed to Acetyl-CoA by the substitution of the carboxylic group with a Coenzyme A by pyruvate dehydrogenase. In real terms, Acetyl-CoA is the molecule that "switch on" the Krebs cycle.
How does galactose enter the Krebs cycle?
Galactose is converted to glucose-6-phosphate, which can enter glycolysis to produce pyruvate. Pyruvate can then be converted to acetyl-CoA, a molecule that enters the Krebs cycle. This allows galactose-derived metabolites to be utilized in the Krebs cycle for energy production.
Cycle formed after pyruvate is produced?
The citric acid cycle, more commonly known as the 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.
