The energy tally from one molecule of pyruvic acid is 4 NADH, 1 FADH₂ and 1 molecule of ATP.
Approximately 30-32 molecules of ATP are produced by oxidative phosphorylation for each glucose molecule that enters glycolysis.
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.
The starting molecule for the Krebs cycle is acetyl-CoA, which enters the cycle by combining with oxaloacetate to form citrate.
The main chemical that enters the mitochondria to continue respiration is pyruvate, which is produced during glycolysis in the cytoplasm. Pyruvate is then converted into acetyl-CoA before entering the citric acid cycle (Krebs cycle) in the mitochondria to produce energy in the form of ATP through oxidative phosphorylation.
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.
Glycolysis (glycos, sugar + lysis, splitting) A glucose molecule is broken down into two molecules of pyruvic acid. The pyruvic acid molecules are then absorbed by the mitochondria. In the mitochondrial matrix, a CO2 molecule is removed from each of the acid molecules. What is left of the pyruvic acid then enters the Krebs cycle.
It is false that if oxygen is present in a cell, pyruvic acid in glycolysis enters the chloroplasts. The pyruvic acid enters the mitochondria if oxygen is present in a cell.

Carbon dioxide. Pyruvic acid undergoes decarboxylation to lose a carbon dioxide molecule and form acetic acid. This acetic acid then combines with Coenzyme A to form acetyl-CoA, which enters the citric acid cycle.
When acetyl CoA and oxaloacetate is present.
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.
Pyruvic acid enters and carbon dioxide exits.
acetyl CoA
Pyruvic acid cycle does enter the Krebs cycle and is turned into acetyl coenzyme A.
