Pyruvate, when channeled into the Kreb's cycle ultimately releases energy in the form of ATP and carbon dioxide.

- Glucose - Which is broken down into 2 Pyruvate -ADP+Pi and NADPH+
In humans, under ANAEROBIC conditions (no O2), pyruvate is 'converted' to lactate, though I wouldn't say it is "broken down".In humans, under AEROBIC conditions (O2 present), pyruvate is converted to Acetyl-CoA, via the pyruvate dehydrogenase reaction.In yeast, pyruvate is converted into ethanol (Party Fluid) via pyruvate decarboxylase and then alcohol dehydrogenase.
Pyruvate/Pyruvic Acid enters the Citric Acid (Kreb's Cycle) and is the first compound used in ATP generation. Two ATP are directly generated during the cycle. A total of 8 NADH and 2 FADH2 are also generated. The NADH and FADH2 are converted to ATP during Oxidative Phosphorylation (sometimes called the Electron Transport Chain).
Pyruvate processing occurs in the matrix of the mitochondria
cytoplasm
A. Glucose is broken down into two molecules of pyruvate Glucose is broken down into two molecules of pyruvate.
Glucose is broken down into pyruvate.
Pyruvate oxidation occurs in the inner membrane of the mitochondria
Glucose is broken down to pyruvate during oxidative phosphorylation.
In the mitochondria
fermentation
- Glucose - Which is broken down into 2 Pyruvate -ADP+Pi and NADPH+
Glucose is broken down into pyruvate.
Glucose is generally not excreted from the body, it can be stored as gyclogen, latter broken down for energy. In which glucose is broken down into pyruvate then into glycolosis for processing Excess glucose can be in the urine if you are diabetic. Glucose can be stored in your liver and in your muscles in the form of glycogen and then released as the cells need glucose for respiration. Glycolysis is the process whereby glucose is cut into two molecules of pyruvate. If oxygen is present, pyruvate will enter the mitochondria and chemical bonds in pyruate will be broken to release energy that will be stored in ATP
2 ATP molecules are used to break the glucose molecule into two pyruvate molecules in the cytoplasm. Then the pyruvate travels to the mitochondria, where it is broken down further and produces 34 ATP molecules, which are used to power a cell.
