RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In microorganisms, the product(s) of anaerobic respiration is/are:
A
Lactic acid
B
Ethanol
C
Carbon dioxide
D
Water
Explanation: 

Detailed explanation-1: -Anaerobic respiration is the breakdown of glucose in the absence of oxygen. In yeast, the glucose breaks down anaerobically to produce alcohol as the end product and carbon dioxide gas as the byproduct. Whereas, in the case of Lactobacillus bacteria, lactic acid is produced anerobically.

Detailed explanation-2: -Anaerobic respiration is the process in which an incomplete breakdown of glucose occurs in the absence of oxygen in the cells. In this process, carbon dioxide and ethyl alcohol are generally produced as the end products.

Detailed explanation-3: -The products of anaerobic respiration are lactic acid, carbon dioxide, and water. Anaerobic respiration is the breakdown of glucose in the absence of oxygen. Inside the cell cytoplasm, glucose breaks down into pyruvic acid. If oxygen is absent, then pyruvic acid converts into lactic acid, carbon dioxide, and water.

Detailed explanation-4: -Since there are two pyruvate molecules, it follows that two carbon dioxide molecules will be produced during anaerobic respiration utilizing the alcoholic fermentation pathway.
