Why is pyruvate converted to lactate? – KnowledgeBurrow.com

Pyruvate is an important chemical compound in biochemistry. It is the output of the metabolism of glucose known as glycolysis. One molecule of glucose breaks down into two molecules of pyruvate, which are then used to provide further energy, in one of two ways. Pyruvate is converted into acetyl-coenzyme A, which is the main input for a series of reactions known as the Krebs cycle (also know… WebGlucose (hexose sugar) is activated for subsequent reactions by its phosphorylation to yield glucose 6-phosphate, with ATP as the phosphoryl donor. This reaction, which is irreversible under intracellular conditions, is catalyzed by enzyme hexokinase, which requires Mg 2+ for its activity. normal bookshelf depth

The enzyme involved is pyruvate carboxylase, which requires ATP and converts pyruvate to oxaloacetate. Oxaloacetate is then converted to phosphoenolpyruvate.

Web(1) A glucose molecule is broken down via glycolysis, yielding two pyruvate molecules. The energy released by this exothermic reactions is used to phosphorylate two ADP molecules, yielding two ATP molecules, and to reduce two molecules of NAD+ to NADH. WebPyruvate is produced by glycolysis in the cytoplasm, but pyruvate oxidation takes place in the mitochondrial matrix (in eukaryotes). So, before the chemical reactions can begin, pyruvate must enter the mitochondrion, …
