Q. Breakdown of pyruvate takes place in _______?
Answer: Glycolysis is the most common mechanism for the breakdown of glucose in bacteria, eukaryotes and the majority of archaea. It is responsible for the production of energy, reduced electron carriers and precursor molecules for the metabolic processes inside cells.
Glycolysis can be integrated with other metabolic processes, which can either be aerobic or anaerobic, despite the fact that glycolysis does not require oxygen. It begins with a molecule of glucose that has six carbons and ends with two molecules of pyruvate, which is a sugar that contains three carbons. Following glycolysis, pyruvate can undergo either aerobic or anaerobic respiration in order to undergo further breakdown and release extra energy.
Pyruvate can be metabolized either in the presence of oxygen or in the absence of oxygen depending on the circumstance. In each scenario, the location of the pyruvate breakdown process might be different.
The cytoplasm is the location where the anaerobic breakdown of pyruvate, which leads to the production of acids and alcohol through fermentation, takes place.
Pyruvate undergoes anaerobic breakdown in the mitochondria by joining the Krebs cycle when oxygen is present. This process is called aerobic respiration.
Pyruvate is broken down in two different ways: one is aerobic and takes place in the mitochondria, while the other is anaerobic and takes place in the cytoplasm.
An essential component of anaerobic respiration is the anaerobic breakdown of pyruvate, which may be found in bacteria. Pyruvate may be broken down anaerobically in the fermentative pathways of bacteria, which results in the production of acids or alcohols and the release of carbon dioxide.
