What are the steps occur when preparing pyruvic acid to enter the citric acid cycle?

1st step is when C2 CoA enters the inner matrix of mitochondrion. So given, C2 + C4 (oxalo-acetic acid) = C6 is also called Citric acid which may came from fruits, then the "lower form" of citric acid is called Isocitric acid(2nd step) but it is still C6 form the 3rd step is when there is a prescence of NAD and that NAD have hydrogen which gives off electron , that made Co2 go out, and because of that you need to subtract everything that goes out , and since carbon is just 1 the equation would be C6(isocitric) minus C1(carbon) = C5 which is called alpha-ketoglutaric acid, then the same process is done again in which there is again a prescence of NAD and that NAD have hydrogen which gives off electron , that made Co2 go out, and because of that you need to subtract again everything that goes out , and since carbon is just 1 the equation would be C5(a-ketoglutaric) minus C1 (carbon) = C4 which is also called Succinic acid. the other four succinic acid are , Fumaric then malic then oxalo-acetic acid , then there is an excess hydrogen again that would be use for mixture of acetyl co enzyme or C2 CoA which is what we did in the first step. Why? In Krebs cycle,. this process is repeated two times.

When does Calvin cycle begin?
When acetyl CoA and oxaloacetate is present.
Does pyruvic acid enters the krebs cycle?
Pyruvic acid cycle does enter the Krebs cycle and is turned into acetyl coenzyme A.
What process occurs after glycolysis?
aerobic oxidatio of pyruvic acid after pyruvic acid is form it get transfer to mitochondria. as soon as pyruvic acid enter to mitochondria it get oxidise to c02 in the reaction called oxidative decarboxylation. here 1st it get decarboxylate and then it get oxidised by the help of enzyme called pyruvate dehydrogenase. nd this enzym is made up of decarboxylase,lipoic acid amid tpp [thiamine pyrophosphate] nd in the presence of some cofactor such as vit b1 nd mg ions. reaction given below pyruvate + NAD+ + co-A = acetyl co-A + NADH + H+ + c02
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.
Why does too much sugar turn to fat?
When glucose is converted into energy, it is broken down into pyruvate and then acetyl-CoA. If energy is required, the acetyl-CoA will enter the Citric Acid Cycle and be used to make ATP. However, if you are not active, then the acetyl-CoA is converted into fat for storage.
Does pyruvic acid enters the krebs cycle?
Pyruvic acid cycle does enter the Krebs cycle and is turned into acetyl coenzyme A.
When does Calvin cycle begin?
When acetyl CoA and oxaloacetate is present.
Can pyruvic acid use in the Krebs cycle?
The pyruvic acid that is produced by glycolysis is used as the initial input for the Krebs Cycle (also called citric acid cycle). In the initial step of the Krebs Cycle, the pyruvic acid is converted to acetyl-CoA via pyruvate decarboxylation. This continues a series of chemical reactions leading to the production of 2 ATP molecules.
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.
How many Krebs cycle occur per glucose?
twice
What can you do with the end product of glycolysis?
The end products of glycolysis enter the Kreb's Cycle or Citric Acid Cycle.
What does Krebs cycle start with?
The answer is pyruvic acid no it's not, this failure up here ↑ is wrong, the answer is acetyl, then two carbon molecules enter the cycle
When glucose is catabolized under aerobic conditions will cross the mitochondrial wall and enter the Kreb's cycle?
pyruvic acid
What must portions of amino acid molecules undergo before they can enter the citric acid cycle?
deamination
Where can Amino acids enter the metabolic pathways?
My test says citric acid cycle, acetyl coA and pyruvate

How many turns can a single glucose molecule drive the Krebs cycle?
A single glucose molecule is able to drive the Krebs cycle 2 times. The Krebs Cycle is the series of chemical reactions that take place to provide all aerobic organisms with the ability to make energy.
