Question

explain the 3 various pathways of break down of glucose in repiration??i need full explanation...​

Answer 1

Answer:

Glucose is broken down into a three carbon molecule called pyruvate in the cell cytoplasm. Pyruvate is broken down in different ways in different organisms as shown below: i.In yeast cells, during fermentation, pyruvate is converted into ethanol and carbon dioxide in the absence of oxygen.

THANK YOU

Answer 2

Answer:

The respiration refers to catabolic process of breakdown of reduced substrates. This

process can occur in presence of oxygen (aerobic respiration) or absence of oxygen (anaerobic respiration). The process of aerobic respiration completely breaks down glucose into carbon dioxide and water, whereas anaerobic respiration incompletely breaks down glucose into alcohol (alcohol fermentation) or lactic acid (lactic acid fermentation).
