Question

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

Answer 1

Aerobic respiration : In this case pyruvate is broken down into waterand 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.
