NEET BIOLOGY

Detailed explanation-1: -The yeast undergoes anaerobic respiration in the absence of oxygen, whereas Amoeba undergoes aerobic respiration in the presence of oxygen.

Detailed explanation-2: -Anaerobic respiration in yeast When yeast cells are reproducing rapidly during beer or wine production, the oxygen is used up. The yeast has to switch to using anaerobic respiration to ensure it can survive. Ethanol and carbon dioxide are produced.

Detailed explanation-3: -This means that in oxygen-free environments they can still survive. The yeast simply switches from aerobic respiration (requiring oxygen) to anaerobic respiration (not requiring oxygen) and converts its food without oxygen in a process known as fermentation.

Detailed explanation-4: -Anaerobic respiration in yeast and plant cells is called alcoholic fermentation, as glucose is broken down to produce ethanol, carbon dioxide, and some ATP. Anaerobic respiration in different microorganisms can be used commercially to produce yoghurt, bread, and alcoholic beverages.
