. In fermentation of yeast
(a) aerobic respiration take place.
(b) anaerobic respiration take place.
(c) inhalation take place.
(d) no respiration.
(b) anaerobic respiration takes place
Yeasts are single-celled microorganisms and are also called anaerobes. These organisms can survive in the absence of oxygen. They get energy through anaerobic respiration. In the absence of oxygen, they breakdown glucose into alcohol and carbon-di-oxide through the process of fermentation.
