How does aerobic and anaerobic respiration compare in yeast?
Yeast can carry out both anaerobic respiration (fermentation) and aerobic respiration. Both produce carbon dioxide, fermentation produces a much lower amount of ATP. Fermentation produces ethanol.
Fermentation - produces a net of 2 ATP (from glycolosis), ethanol and carbon dioxide.
Aerobic respiration - produces 36-38 ATP, carbon dioxide and water.
Here is a video which shows an experiment using yeast fermenting a solution of sugar water. Yeast cells can carry out either fermentation or aerobic respiration depending on environmental conditions.
Here is a video which summarizes both aerobic and anaerobic respiration.
