NEET BIOLOGY

Detailed explanation-1: -Anaerobic respiration occurs in yeast. Yeast help in the fermentation of various products and that’s why carbon dioxide is released during the process.

Detailed explanation-2: -Anaerobic respiration is a type of cellular respiration where respiration takes place in the absence of oxygen. It takes place in the cytoplasm since most anaerobic cells do not have specialized organelles whereas aerobic respiration takes place in the mitochondria.

Detailed explanation-3: -Anaerobic respiration, which takes place in the cytoplasm of a cell, can occur in the absence of oxygen, as it only requires glucose. In animal cells and some bacterial cells, anaerobic respiration produces lactic acid. In yeast and plant cells, anaerobic respiration produces ethanol and carbon dioxide.

Detailed explanation-4: -In the presence of oxygen, yeast undergo aerobic respiration and convert carbohydrates (sugar source) into carbon dioxide and water. In the absence of oxygen, yeasts undergo fermentation and convert carbohydrates into carbon dioxide and alcohol (Figure 2).
