Question

What are the different ways in which glucose is oxidised to provide energy in various

organisms? Also write the steps involved in the breakdown of food.​

Answer 1

Answer:

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.

Different ways in which glucose breaks down

Anaerobic Respiration. The anaerobic respiration process takes place in the absence of oxygen. ...

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. ...

Lack of Oxygen.

Glucose can be broken down in two ways in the absence of oxygen or in anaerobic conditions: (i)First step is breakdown of glucose molecule into pyruvate which takes place in cytoplasm. Whenever there is lack of oxygen in our muscle cells (due to excessive exercise), pyruvate is broken down to lactic acid
