give the pathway by which breakdown of glucose molecules takes place
The process of breakdown of glucose molecules involves two major stages - glycolysis (anaerobic respiration) and aerobic respiration ( Kreb’s cycle and ETS Pathway).
Glycolysis
Cellular respiration begins at this stage in the cytoplasm of the cells, and yields 2 carbon-based molecules called pyruvate, and 2 molecules of ATP. Oxygen plays no part during this stage, so it is called anaerobic respiration.
