Question

what are the diffrent ways in which glucose is used to provide energy in various organisims

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

Answer-

Anaerobic Respiration

The anaerobic respiration process takes place in the absence of oxygen. For example: In yeast during fermentation. In this process, the pyruvate is converted into ethanol and carbon dioxide.

Aerobic Respiration

In aerobic respiration, breakdown of pyruvate takes place in the presence of oxygen to give rise to 3 molecules of carbon dioxide and water. The release of energy in aerobic respiration is much more than anaerobic respiration.
