Question

state the pathway of breakdown of glucose oxidation in absence of oxygen is yeast cell

Answer 1

Explanation:

Glucose is broken down into a three carbon molecule called pyruvate in the cell cytoplasm. ... i.In yeast cells, during fermentation, pyruvate is converted into ethanol and carbon dioxide in the absence of oxygen.

Answer 2

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. Pyruvate is broken down in different ways in different organisms .

• In yeast cells, during fermentation, pyruvate is converted into ethanol and carbon dioxide in the absence of oxygen.
• In mitochondria, breakdown of pyruvate takes place in presence of oxygen to give rise three molecules of carbon dioxide and water.
• Sometimes, when there is lack of oxygen, especially during vigorous activity, in our muscles, pyruvate is converted into lactic acid.
