Question

explain different path ways of glucose oxidation in living organisms​

Answer 1

Answer:

After conversion of glucose into pyruvate , energy can be released by any of the 3 pathways . 1. by aerobic respiration - Pyruvate is oxidized in the presence of enough oxygen to release water, carbon dioxide and energy in the form of 38 ATPs. ... fermentation-This pathway is followed by yeast to respire.

Answer 2

Answer:

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.
