Question

Explain the ways in which glucose is broken down in absence of oxygen

Answer 1

anaerobic respiration takes place.
in the following case, there is a build up of lactic acid in muscles during vigorous excercise. the lactic acids needs to be oxidized to carbon dioxide and water. this formation of lactic acid results in muscle pains .

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
