Question

What are the different ways in which glucose is oxidized to provide energy in various organisms?

Answer 1

1) Anaerobic respiration: Here the first step is the breaking down of glucose into a three carbon molecules called pyruvate.This process takes place in the cytoplasm. Further, the pyruvate may be converted into ethanol and carbon dioxide.
2) Aerobic respiration: During aerobic respiration, first glucose is broken down into pyruvate and then the three - carbon pyruvate molecule is broken down to give three molecules of carbon dioxide and water.
