Glucose is a six carbon sugar when glycolysis is over it is split into two three carbon molecules called pyruvic acid (pyruvates). When this is done the link cycle begins (second stage of respiration) . In the link reaction the pyruvic acid loses a carbon that becomes CO2. The remaining two carbons are called acetic acid. This then meets enzyme coenzyme A and becomes acetylcoenyme A. This combination is the start of the kreb's cycle.
Pyruvates enter the Krebs Cycle
Glucose is reduced. During glycolysis, glucose is reduced to two pyruvates, which have 3 carbons. The pyruvates enter the mitochondria to be used in Kreb cycle.
Attached to coenzyme A as acetyl-CoA. This is the molecule that enters the Krebs
When pyruvic acid produces by glycolysis enter the mitochondrion.
they will enter the Krebs cycle
glycolysis yiels 2 pyruvate molecules that will undergo Kreb's cycle
Glycolysis itself does not output CO2. Just after glycolysis the 2 pyruvates which are derived from the glucose molecule during glycolysis, are converted into 2 acetyl CoA in the process of which one CO2 per pyruvate is released.After that the 2 acetyl CoA's enter the Kerbs cycle and a further 2 CO2's are produced for each.In total 6 CO2's are created after glycolysis2 during the conversion of pyruvates to Acetyl CoA4 Durint the TCA/ Citric Acid/ Kerbs Cycle
because from glycolisis comes pyruvate, and then it is turned into acetylCoA. Without acetylCoA, nothgn will be able to enter the Krebs Cycle, otherwise known as the Citric acid cycle. Once the AcetylCoA comes in, after the prep cycle, it can then bind to RuBp, turnign into a six carbon sugar.
The pyruvates enter the mitochondria to further undergo cellular respiration. The ATP molecules are used by the cell.
Pyruvic acid cycle does enter the Krebs cycle and is turned into acetyl coenzyme A.
The end products of glycolysis enter the Kreb's Cycle or Citric Acid Cycle.
They enter the Krebs Cycle.
1 glucose ------by glycolysis end up with 2 molecules of pyruvic acid. one pyruvic = 3 carbon > 2 pyruvic acid enter to kerb cycle after changing to Acetyl CO A So this means 1 glucose drive the Krebs cycle two times
Pyruvic acid is the end product of glycolysis that enters the mitochondria for the Kreb's cycle. Pyruvic acid however does not enter the mitochondria in the acid form; instead it enters in the form of salts and as the anionic pyruvate.
In the Kreb's Cycle and in the short reaction when the pyruvates enter the mitochontria.
After the Krebs cycle, NADH2 and FADH2 enter the electron transport chain where ATP and water are produced by Hydrogen Atoms.

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 high E electrons that enter Krebs are used to reduce carbon dioxide to carbohydrate. Not all high E electrons that leave the light-dependent reactions go to the Krebs cycle. Some are used to produce the ATP that drives the endergonic Krebs cycle.
