Question

When oxygen is absent the end product of glycolysis is converted to?

Answer 1

Glycolysis:

1. Glycolysis is a process in which cells will break down glucose and release energy in the form of adenosine triphosphate- ATP.
2. Output of glycolysis is two molecules of pyruvate, adenosine triphosphate (ATP), nicotinamide adenine dinucleotide (NADH) and water.
3. Glycolysis occurs in both aerobic and anaerobic organisms.
4. When oxygen is absent pyruvate is converted to lactic acid or ethanol and CO₂ by fermentation.
5. Fermentation is a process in which substances break down into simpler substances without the help of oxygen.
6. Hence this is also called as anaerobic respiration.
