Question

Explain the breakdown of glucose by various pathways?​

Answer 1

Answer:

Glucose is broken down into a three carbon molecule called pyruvate in the cell cytoplasm. Pyruvate is further broken down by different ways to provide energy in various organisms. ... i.In yeast cells, during fermentation, pyruvate is converted into ethanol and carbon dioxide in the absence of oxygen.

Answer 2

Answer:

Hey mate

Here your answer

The biochemical oxidation of nutrients takes place in different ways in different organisms. Some organisms use oxygen to break down glucose completely into carbon dioxide and water, while others do not.

However, the first step, i.e. Break down of glucose, a 6 molecules into a 3 carbon molecules called pyruvate (or pyruvic acid) is common to all. This process of conversion of glucose to pyruvate, i.e. Glycolysis takes place inside the cytoplasm of the cell. After this, the conversion of pyruvate into another substance depends on the presence or absence of oxygen.
