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.
During glycolysis glucose is oxidized into?
In cellular respiration, glucose is oxidized into 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 molecule is the output of glycolysis and is quickly converted to Acetyl CoA before the beginning of the citric acid cycle?
Pyruvate is the molecule that is the output of glycolysis and is quickly converted to Acetyl CoA before entering the citric acid cycle. This conversion occurs in the mitochondria through a process called pyruvate decarboxylation, where pyruvate loses a carbon dioxide molecule and forms Acetyl CoA.
Which of the following produces nadh ATP and two pyruvate molecules electron transport chaincalvin cycleglyclosesiskreb cycle?
The Krebs cycle produces NADH, ATP, and two pyruvate molecules. The electron transport chain generates a large amount of ATP by oxidative phosphorylation. The Calvin cycle is involved in carbon fixation during photosynthesis. Glycolysis, on the other hand, is a metabolic pathway that breaks down glucose to produce ATP and pyruvate.
Is acetyle coenzyme a formed from the breakdown of pyruvic acid?
Precisely, it is called pyruvate decarboxylation. The COOH group Pyruvate is removed as CO2, and Acetyl CoA from Coenzyme A is added in an NAD+ dependent manner by the enzyme decarboxylase.
Which of the following choices is responsible for the decarboxylation in the pyruvate dehydrogenase complex?
Thiamine pyrophosphate (TPP)
Name a molecule that joins in a reaction to make acetyl-coa?
Pyruvate is a molecule that joins in a reaction to form acetyl-CoA through the process of pyruvate decarboxylation.
Is Co2 released during oxidation of pyruvate to acetyl CoA?
Yes, during the oxidation of pyruvate to acetyl CoA in the mitochondria, CO2 is released through decarboxylation reactions. This process is part of the pyruvate dehydrogenase complex, where pyruvate is converted to acetyl CoA, releasing CO2 as a byproduct.
Name the two step process where pyruvate is converted to a two carbon compound releasing carbon dioxide. Then the electrons are transferred from a molecule of NADH to the two carbon compound producing?
Pyruvate decarboxylation -> Acetaldehyde reduction The product is ethanol. Pyruvate decarboxylation is performed by pyruvate decarxylase with cofactor thiamine pyrophosphate, and the product, acetaldehyde, is reduced by NADH. (Pyruvate decarboxylase is NOT the same as the pyruvate dehydrogenase complex in cellular respiration. Though pyruvate dehydrogenase also decarboxylates pyruvate, but the decarboxlated species immediately reacts with CoA to form acetyl-CoA).
Glycolysis produces pyruvate. The fate of this pyruvate depends mainly on the availability of which of the following?
Molecular oxygen
What happens immendiately after pyruvate is brought into the mitochondria?
After pyruvate is brought into the mitochondria, it undergoes a series of enzymatic reactions called pyruvate decarboxylation. In this process, pyruvate is converted into acetyl-CoA, which can then enter the citric acid cycle (also known as the Krebs cycle or TCA cycle) to produce energy in the form of ATP.
What stage of cellular respiration pyruvate as a product?
the krebs cycle produces pyruvate as a product to be used by the ATP molecules.
What breaks down pyruvate down into carbon dioxide?
Krebs cycle
What metabolites enter the citric acid cycle and is formed in part by the removal of a carbon from one molecule of pyruvate?
Acetyl-CoA is the metabolite that enters the citric acid cycle and is formed in part by the removal of a carbon from one molecule of pyruvate through a process called pyruvate decarboxylation.
What happens immediately after pyruvate brought into the mitochondrion?
Acetyl CoA forms.
What is pyruvate converted to in the mitochondria of a cell?
Pyruvate is converted to acetyl-CoA in the mitochondria of a cell through a series of enzymatic reactions known as pyruvate decarboxylation. This conversion is a crucial step in the process of cellular respiration, where acetyl-CoA enters the citric acid cycle to generate ATP.
