How many co2 molecules are generated from each pyruvate that enter the mitochondrion?
In the decarboxylation of Pyruvate to form Acetyl CoA, one Carbon atom is lost as co2.
Acetyl CoA can then be used in the citric acid cycle in which another two co2 molecules are produced.
It is important to note however, that neither Pyruvate nor Acetyl CoA will necessarily follow this pathway, since they are also required for various other processes.

What purpose does pyruvic acid serve?
Pyruvic acid (or pyruvate) is simply one of the compounds in the metabolic pathway from sugars to carbon dioxide and water. From pyruvate (a three cabon unit) either one of two reactions can occur. It can react to form lactose or lose a carbon dioxide molecule to become a two carbon unit and enter the Krebs cycle.
Why are pores in the cell membrane different sizes?
They selectively allow certain size molecules to enter, or not to enter, the cell.
What is vaporization throughout a liquid?
You may be referring to boiling. First a little background.Vaporization is a phase change from the liquid state to the gaseous (or vapor) state. When a liquid vaporizes or evaporates, the more energetic molecules in the liquid leave the surface and enter the vapor phase in the air above the liquid. Because its the more energetic molecules that leave the liquid, and the kinetic energy of a molecules is related to the temperature, vaporization is a cooling process. Another term for this is endothermic, meaning it takes in heat.When a liquid is below its boiling point, not all molecules uniformly have enough energy to enter the vapor state. Some molecules have more energy and go into the vapor, others don't and stay behind in the liquid state. As an average, the liquid exhibits a vapor pressure less than that of the atmosphere. The vapor pressure of a liquid is a function of its temperature.When a liquid reaches its boiling temperature, however, that means the liquid's vapor pressure (as a whole) equals that of the atmosphere. So instead of evaporation just from the surface, now you see bubble of water vapor forming throughout the liquid and rising to the surface.

What happen to sugar and oxygen in the mitochondrion?
These molecules enter cellular respiration process to yield energy .
What are two reactants that enter the mitochondrion?
Glucose and Oxygen
What has to be present for Pyruvate to enter the mitochondria?
The mitochondrial membrane has special transporter proteins which are needed to transport pyruvate. This transport also requires ATP.
What are the protein substances required to break down pyruvate?
Enzymes that are involved in the breakdown of pyruvate include pyruvate dehydrogenase complex (PDC) and pyruvate carboxylase. These enzymes are crucial in converting pyruvate into acetyl-CoA to enter the citric acid cycle for further energy production.
Which molecule is formed when glucose is broken in half?
When glucose is broken in half through the process of glycolysis, two molecules of pyruvate are formed. Pyruvate is a three-carbon compound that can then enter the citric acid cycle for further energy production.
What materials enter glycolisis?
Glucose enters into it.Then converted into pyruvate.
Do pyruvate molecule which is the product of glycolysis enters the mitrochondria during cellular respiration?
Yes, pyruvate molecules produced during glycolysis enter the mitochondria where they undergo further chemical reactions in the citric acid cycle to generate energy in the form of ATP. This process occurs in the matrix of the mitochondria.
How does the pyruvate produced by glycolysis enter the mitochondrion?
Pyruvate enters the Krebs cycle via an intermediate called acetyl CoA.Pyruvate is formed in the cytoplasm as the end product of glycolysis. Pyruvate enters a mitochondrion, in the matrix of which it encounters the enzyme pyruvate dehydrogenase. This enzyme catalyzes the reaction of pyruvate with coenzyme A to form acetyl CoA. This reaction is sometimes called the link reaction, as it links glycolysis to the Krebs cycle (= citric acid cycle, or tricarboxylic acid cycle)."Pyruvate dehydrogenase" is in fact a huge complex (bigger than a ribosome) consisting of three enzymes and a number of other substances, including coenzymes. In the course of the reaction NAD+ is reduced to NADH. A molecule of CO2 is also produced. So this reaction involves a both an oxidation and a decarboxylation.Acetyl CoA then reacts with oxaloacetate to form citrate. Both oxaloacetate and citrate are intermediates of the Krebs cycle.
Describe a pathway used for degradation of carbohydrates?
Carbohydrates are broken down through a process called glycolysis, which involves a series of enzymatic reactions that convert glucose to pyruvate. Pyruvate can then enter the citric acid cycle to generate energy through the oxidation of acetyl-CoA. In the absence of oxygen, pyruvate can be converted to lactate or ethanol through fermentation pathways.
How many carbons from 1 glucose molecule enter 1 round of the Krebs cycle?
Two carbons from one glucose molecule enter one round of the Krebs cycle in the form of acetyl-CoA, which is derived from pyruvate through pyruvate dehydrogenase.
