Question

what are the different ways in which glucose is oxidised to provide energy in various organisms?

Answer 1

Name the twO ways in which glucose is oxidized to provide energy : various Organisms. Answer: 1) Anaerobic respiration: Here the first step is the break-down of glucose into a three-carbon molecule called pyruvate.

Answer 2

1) Aerobic respiration : In this case pyruvate is broken down into water and carbon dioxide along with release of energy. It commonly occurs in mitochondria of cells. 2) Anaerobic respiration in yeast : In yeast cells during fermentation pyruvate is converted into ethanol and C02 in the absence of 02.
