Question

biochemical process during which glucose is oxidised​

Answer 1

Glycolysis, the initial stage of glucose metabolism, takes place in the cytosol and does not involve molecular O2. It produces a small amount of ATP and the three-carbon compound pyruvate. In aerobic cells, pyruvate formed in glycolysis is transported into the mitochondria, where it is oxidized by O2 to CO2.

Answer 2

Explanation:

Two ways in which glucose is oxidized to obtain or produce energy are as follows-

1) Anaerobic respiration: This process involves the breakdown of glucose into a three-carbon molecule called pyruvate in the absence of oxygen and takes place in the cytoplasm.

This pyruvate so produced can be converted into ethanol and carbon dioxide.

This process commonly takes place in yeast.

2) Aerobic respiration: During aerobic respiration (in the presence of oxygen), glucose is broken down into pyruvate and then this pyruvate molecule is broken down to give rise to three molecules of carbon dioxide and water.
