Question

explain the ways in whic gulucose is break down in shortage or absence of oxygen

Answer 1

In the absence of oxygen When breakdown of glucose is carried out in the absence of oxygen in a cell, it is called as anaerobic respiration. This process is called as fermentation in microbes. Ethyl alcohol or lactic acid is produced by the breakdown of pyruvate.

Answer 2

Anaerobic Respiration is the type of Respiration which occurrs in absence of oxgen Glucose breakdown in intially results in the formation of Pyruvate + energy

In human cells it results in the formation of

lactic acid + energy

and in the cells of yeast

In the formation of ethanol +carbon dioxide + energy

In yeast and humans cells the breakdown Pyruvate occurs in the absence of oxygen this is also known as cellular respiration
