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.
Pyruvate is converted to acetyl-coa releasing CO2. Acetyl-CoA then goes into the creb cycle. In this process it gives off an extra 2 molecules of CO2. This results in 3 molecules of CO2 from one molecule of pyruvate.
Complete oxidation of one glucose molecule will yield six CO2. Since one glucose can produce 2 pyruvate in glycolyis, this would make three CO2 per pyruvate. Pyruvate enters Kreb's cycle in mitochondria after converted into acetyl-CoA.
A molecule of pyruvic acid (C3H4O3) contains 3 carbon atoms, so one molecule of pyruvic acid will form 3 molecules of carbon dioxide when it is completely oxidized to CO2 and water.
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.
They selectively allow certain size molecules to enter, or not to enter, the cell.
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.

Glucose and Oxygen
The electrons move
Glucose enters into it.Then converted into pyruvate.
The mitochondrial membrane has special transporter proteins which are needed to transport pyruvate. This transport also requires ATP.
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.
The series of biochemical reactions in which glucose is broken down to pyruvate with the release of usable energy in the form of ATP. One molecule of glucose undergoes two phosphorylation reactions and is then split to form two triose-phosphate molecules. Each of these is converted to pyruvate. The net energy yield is two ATP molecules per glucose molecule. In aerobic respiration pyruvate then enters the citric-acid-cycle. Alternatively, when oxygen is in short supply or absent, the pyruvate is converted to various products by anaerobic respiration. Other simple sugars, e.g. fructose and galactose, and glycerol (from fats) enter the glycolysis pathway at intermediate stages.
In humans, pyruvate cannot be directly converted into glucose through a process called gluconeogenesis. This is because humans lack the specific enzymes required to convert pyruvate into glucose. Pyruvate can be converted into lactate or acetyl-CoA, which can then enter various metabolic pathways in the body.
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.
Other sugars do enter into glycolysis such as fructose, galactose and mannose. Fructose can directly enter into glycolysis while the other two is converted to a glucose intermediate molecule because it can produce the two triose phophate molecules (DHAP and G3P) which are needed to generate energy from the reactions (ATP) and pyruvate.
