Question

3. What are different ways in which glucose is oxidised to provide energy in various organisms? What is main
difference between aerobic and anaerobic respiration?
​

Answer 1

Explanation:

The anaerobic respiration process takes place in the absence of oxygen. For example: In yeast during fermentation. In this process the pyruvate is converted into ethanol and carbon dioxide.

Aerobic respiration needs oxygen to occur, while anaerobic does not. This presence of oxygen determines what products will be created. During aerobic respiration, carbon dioxide, water, and ATP are produced. During anaerobic respiration, lactic acid, ethanol, and ATP are created.

Answer 2

Answer:

Explanation:

the two different ways in which glucose is oxidized to provide energy in various organisms are as follows: First set of breakdown of glucose (six carbon molecules) takes place in the cytoplasm of cells of all organisms. This process yields a three carbon molecule compound called pyruvate

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.

Anaerobic respiration yeast : In yeast cells during fermentation pyruvate is converted into ethanol and C02 in the absence of 02
