Question

How is glucose oxidised to get energy in various organisms​

Answer 1

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.

Answer 2

Explanation:

The different ways in which glucose is oxidised to provide energy in various organisms are :

1 . Aerobic respiration - It is done in the presence of oxygen.

2. Anaerobic respiration - It is done in the absence of oxygen.
