Before the Krebs cycle can begin pyruvate molecules must move from the cytoplasm into the?
Before the Krebs cycle can begin, pyruvate molecules must move from the cytoplasm into the mitochondria. Once inside the mitochondria, each pyruvate is converted into acetyl-CoA through a process called pyruvate decarboxylation. This conversion also produces carbon dioxide and NADH, which are important for cellular respiration. Acetyl-CoA then enters the Krebs cycle to facilitate energy production.

In aerobic respiration glucose molecules are converted into acetyle CoA molecules when they enter?
In aerobic respiration, glucose molecules are converted into acetyl CoA during a process called pyruvate oxidation. After glycolysis, which occurs in the cytoplasm, glucose is broken down into two molecules of pyruvate. These pyruvate molecules then enter the mitochondria, where they undergo decarboxylation, releasing carbon dioxide and forming acetyl CoA. This acetyl CoA then enters the Krebs cycle, where it plays a crucial role in energy production.
How many times must the Krebs cycle run for one molecule of pyruvate?
The Krebs cycle, also known as the citric acid cycle, must run once for each molecule of pyruvate. Since one glucose molecule produces two pyruvate molecules during glycolysis, the Krebs cycle runs twice for each glucose molecule. Therefore, for one molecule of pyruvate, the cycle runs just once.
How many cycle after Krebs reaction one glucose molecule has been broken down to CO2?
One glucose molecule undergoes glycolysis, which breaks it down into two molecules of pyruvate. Each pyruvate then enters the Krebs cycle (or citric acid cycle), where it is fully oxidized. Since each glucose results in two pyruvate molecules, two cycles of the Krebs cycle occur per glucose molecule, leading to the production of CO2 as a byproduct in each cycle. Therefore, a total of six CO2 molecules are generated from one glucose molecule after two Krebs cycles.
What process occurs before the Krebs cycle?
The formation of acetyl-CoA
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.
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 is the end result of glycolysis that eventually feeds into the Krebs cycle?
The end product of glycolysis is pyruvate, which is converted into acetyl-CoA before entering the Krebs cycle. Acetyl-CoA combines with oxaloacetate to initiate the Krebs cycle, where it undergoes a series of reactions to produce ATP and high-energy electron carriers.
How many molecules of CO2 are released during the Krebs cycle?
For every molecule of pyruvate entering the Krebs cycle, 3 molecules of CO2 are released. Since each glucose molecule produces 2 molecules of pyruvate through glycolysis, the total number of CO2 molecules released per glucose molecule in the Krebs cycle is 6.
What happens to pyruvate molecules formed glycolysis in the absence of oxygen?
they will enter the Krebs 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.
In aerobic respiration glucose molecules are converted into acetyle CoA molecules when they enter?
In aerobic respiration, glucose molecules are converted into acetyl CoA during a process called pyruvate oxidation. After glycolysis, which occurs in the cytoplasm, glucose is broken down into two molecules of pyruvate.

This acetyl CoA then enters the Krebs cycle, where it plays a crucial role in energy production.
What does one pyruvate produce after the Krebs cycle?
One pyruvate molecule produces 3 molecules of carbon dioxide, 4 molecules of NADH, 1 molecule of FADH2, and 1 molecule of ATP after completing the Krebs cycle. These molecules are important for generating energy through the electron transport chain.
How many molecule of carbon dioxide are produce when Krebs cycle operates once?
One molecule of glucose is broken down into two molecules of pyruvate during glycolysis. Each pyruvate molecule then enters the Krebs cycle and is fully oxidized to produce three molecules of carbon dioxide. Therefore, in total, six molecules of carbon dioxide are produced when the Krebs cycle operates once.
How many times must the Krebs cycle run for one molecule of pyruvate?
The Krebs cycle, also known as the citric acid cycle, must run once for each molecule of pyruvate. Since one glucose molecule produces two pyruvate molecules during glycolysis, the Krebs cycle runs twice for each glucose molecule. Therefore, for one molecule of pyruvate, the cycle runs just once.
