Question

Based on your understanding of cellular respiration, explain in detail the main difference between aerobic and anaerobic cellular respiration. Use detail.

Answer 1

Aerobic respiration needs oxygen to occur, while anaerobic does not.

The key difference between aerobic respiration and anaerobic respiration is that in aerobic respiration the electron transport system's terminal electron acceptor is oxygen

In anaerobic respiration the terminal electron acceptor is something other than oxygen, such as nitrate, nitrite, fumarate, DMSO, etc.

During aerobic respiration, carbon dioxide, water, and ATP are produced.

During anaerobic respiration, lactic acid, ethanol, and ATP are created.

Aerobic respiration occurs in mitochondria cells but anaerobic respiration occurs in the cytoplasm of cells.

Aerobic respiration used when heart rate and breathing rate rise but in anaerobic respiration used during the first 1-2minutes of exercise.
