Which type of respiration produces lactic acid as a byproduct?

Anaerobic respiration is the process that occurs when the body converts glucose into energy without the presence of oxygen. This type of respiration is particularly important during high-intensity exercise when oxygen levels are insufficient to meet energy demands. As glucose is broken down in the absence of oxygen, lactic acid is produced as a byproduct.

The accumulation of lactic acid in muscles can lead to fatigue and soreness, which often occurs after intense physical activity. This is contrasted with aerobic respiration, where oxygen is present and the end products are carbon dioxide and water, without the creation of lactic acid. Ethanol fermentation is another form of anaerobic respiration, but it specifically produces ethanol and carbon dioxide rather than lactic acid. Cellular respiration encompasses both aerobic and anaerobic processes but does not specify which byproduct is produced. Therefore, the correct association of lactic acid production is indeed with anaerobic respiration.
