Question

Name the type of respiration in which the end products are:

C₂H₅OH and CO₂

Give one example where such a respiration can occur.

Answer 1

The type of respiration that produces C₂H₅OH (ethanol) and CO₂ (carbon dioxide) is anaerobic respiration (specifically known as alcoholic fermentation).

For example, this type of respiration occurs in yeast cells when they break down sugar in the absence of oxygen. It also occurs in certain anaerobic bacteria and in germinating seeds that are waterlogged and deprived of air.
