Question

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

Answer 1

Answer:

Anaerobic Respiration

Explanation:

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.

Answer 2

Answer :

A. Breaking down of glucose involves two processes. In the first step, it is broken into three carbon molecules called pyruvate. The pyruvate is further broken down into energy in following different ways in various organisms.

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.

3) Anaeorbic respiration in muscles: Due to lack of oxygen, eg. during vigorous running or exercise, in human muscles, pyruvate is converted to lactic acid.
