Question

what is pyruvate? also tell how glucose break ?​

Answer 1

Heya friend,

Here is your answer.. :)

__________________

            Pyruvate is an important molecule that is present at the intersection of multiple biochemical pathways. It is commonly encountered as one of the end products of glycolysis, which is then transported to the mitochondria for participating the citric acid cycle. In the absence of oxygen, or when oxygen demand outstrips supply, pyruvate can undergo fermentation to produce lactate. Both pyruvate and lactate can be used to regenerate glucose as well•••

              In the absence of oxygen, glucose is broken down into lactic acid and produce two molecules of ATP in animals. And in plants, glucose is broken down into ethanol and CO2 and produce 2 molecules of ATP. The whole process is done in cytoplasm of the cells in the absence of oxygen•••
