Question

Name the type of respiration in which the end product is:

Lactic acid

Give one example where such a respiration can occur.

Answer 1

The type of respiration that produces lactic acid is anaerobic respiration (specifically known as lactic acid fermentation).

For example, this respiration occurs in human muscle cells during intense physical exercise (such as sprinting, heavy weightlifting, or fast swimming) when oxygen cannot be supplied to the tissues quickly enough to meet their energy demands. It also occurs in Lactobacillus bacteria during the process of turning milk into curd.
