Question

explain three pathway of break down of Glucose in living organism​

Answer 1

At first, glucose is broken down into three-carbon molecule called pyruvate. Pyruvic acid is converted into carbon dioxide, and water thus releasing a lot of energy. ... (ii) Anaerobic respiration takes place in the cytoplasm in the absence of oxygen.

Answer 2

Answer:

Glucose is first converted into pyruvate. We all know that the glucose broken

down into carbon molecules.

This process of breaking down happened in the

cytoplasm of the cells.

1) (Anaerobic respiration) Breakdown of pyruvate take place in absence of oxygen.Pyruvate is broken down into ethanol and carbon dioxide. (in case of microbes, i.e., fermentation in yeast)

2)(Aerobic respiration) Breakdown of pyruvate takes place in presence of oxygen. Pyruvate is broken down into carbon dioxide and water. (in mitochondria)

3)During strenuous physical activity, the energy demand from muscle cells suddenly increases. This is compensated by anaerobic respiration in muscle cells. In such a situation, pyruvate is broken down into lactic acid. (In muscle cells)
