Anaerobic respiration in yeast, also known as alcoholic fermentation, is correctly represented by equation R: 'Glucose gives alcohol + carbon dioxide.' In this process, yeast cells break down glucose in the absence of oxygen to produce ethanol and carbon dioxide. This is crucial in industries such as brewing and baking, where yeast ferments sugars to produce alcohol and gas.Equation P represents photosynthesis, which is unrelated to respiration, while equation Q represents aerobic respiration that requires oxygen, unlike the anaerobic process in yeast.

This equation represents photosynthesis, where carbon dioxide and water are converted into glucose and oxygen. This is not related to respiration in yeast.

This equation represents aerobic respiration, where glucose and oxygen are used to produce carbon dioxide and water, along with energy. Yeast can perform this process but it is not anaerobic.

This equation represents anaerobic respiration in yeast, known as alcoholic fermentation, where glucose is converted into alcohol and carbon dioxide in the absence of oxygen.

Incorrect. Only equation R represents anaerobic respiration in yeast. Equations P and Q involve processes that require oxygen.
