Question

what are the different ways in which glucose is oxides to provides energy in various organisms

Answer 1

In the absence of oxygen glucose is breakdown into pyruvate which take place in cytoplasm

The anaerobic breakdown in bacteria is called fermentation during fermentation pyruvate is broken down to ethyl alcohol and carbon dioxide

When there is lack of oxygen in our muscle cell pyruvate is broken down to lactic acid

Answer 2

This is your answer. The first step of conversion of glucose into pyruvic acid is common in all organisms. Then it varies on the amount of oxygen available to the organisms. Thank you
