Anaerobic respiration is cellular respiration in the absence of oxygen molecules. In yeast, the process of glycolysis occurs followed by alcohol fermentation. Thus, option B is correct.
<h3>What is glycolysis and alcohol fermentation?</h3>
Glycolysis is the cellular-metabolic process where the energy is produced from the splitting of the glucose molecule. As a result, ATP, water, pyruvate, and NADH are produced from glucose.
Followed by glycolysis occurs alcohol fermentation where the yeast produces carbon dioxide and ethanol from the sugar molecules like glucose and sucrose. Also, energy in the form of ATP is released for cellular activity.
Therefore, option B. glycolysis followed by alcohol fermentation is the correct pathway of anaerobic respiration in yeast.
