Question

In which part of cell does glucose breakdown in pyruvate. Trace the breakdown of pyruvate in lack of oxygen. In which cell of human body does it take place?name the energy currency of the cell.

Answer 1

Glucose breaks down in cytoplasm (in the cellular matrix called cytosol) into pyruvate. They then enter into the mitochondrion of the cell.
In the absence of oxygen (anaerobic conditions) pyruvate undergoes fermentation either lactic acid fermentation or alcohol fermentation. In this fermentation reaction NO ATP molecules is generated, however reduced NAD+ is generated from fermentation. The NAD+ regenerated is used in the glycolysis process to make ATP.
ATP -Adenosine Tri Phosphate is the energy currency of the cell.

Answer 2

Breakdown of glucose occur in cytoplasm of cell and the energy currency of is ATP. ATP is released in the process of respiration
