Question

what is the advantage and disadvantage of fermentation and aerobic respiration​

Answer 1

Answer:

Advantages: Aerobic respiration generates a large amount of ATP. .Aerobic and anaerobic respiration each have advantages under specific conditions. Aerobic respiration produces far more ATP, but risks exposure to oxygen toxicity. Anaerobic respiration is less energy-efficient, but allows survival in habitats which lack oxygen

Disadvantages: Aerobic respiration is relatively slow and requires oxygen

Fermentation

Advantages

1. Fermentation is an anaerobic process, so can occur even when there is insufficient oxygen in the cell.

This is what allows our skeletal muscles to continue working even after strenuous exercise has made our muscles use up oxygen faster than it can be supplied from the bloodstream.

2. Fermentation is a much simpler process than, and is also faster than, aerobic respiration.

For example, lactate fermentation is a single reaction. On the other hand, in the mitochondria, the pyruvates have to be processed by a few steps to produce acetyl CoA, which then must enter the citric acid cycle and undergo all those reactions, and then the NADH and FADH2 have to donate their electrons to the electron transport chain, and the electrons have to be passed through the complexes and down to oxygen, and the protons have to flow back through ATP synthase.

Disadvantages

1. Fermentation produces no ATP.

When fermentation occurs, the only ATP that is produced is produced by glycolysis, not by fermentation itself. And glcolysis produces only 2 net ATP per glucose.

Compare that to the ~28 additional ATP produced by the mitochondria per starting glucose, for a total of about 30 ATP per glucose.
