Question

Mention two ways in which food get oxidized in organisms.
please give correct answer i will mark as brainliest

Answer 1

Answer:

In the presence of sufficient Oxygen, Pyruvate molecules are broken down into Water and Carbon dioxide and Energy is released. This process is called aerobic respiration. In the lack of oxygen, Pyruvate molecules are converted into lactic acid and energy is released.

Answer 2

Answer:

Anaerobic respiration

Aerobic respiration

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.
