Question

what are the different ways in which glucose is oxidised to
Provide energy Various Organisms ? (a)​

Answer 1

Explanation:

The two different ways in which glucose is oxidized to provide energy in various organisms are as follows: First set of breakdown of glucose (six carbon molecules) takes place in the cytoplasm of cells of all organisms. This process yields a three carbon molecule compound called pyruvate.

Answer 2

Explanation:

1. Anaerobic Respiration

This process takes place in absence of oxygen, e.g. in yeast during fermentation. In this case pyruvate is converted into ethanol and carbon dioxide

2. Aerobic Respiration

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

3. Lack of Oxygen

Sometimes when there is lack of oxygen, especially during vigorous activity in our muscles, pyruvate is converted into lactic acid Formation of lactic acid in muscles causes cramp
