Detailed explanation-1: -(b) Carbon dioxide is given out. In anaerobic respiration, glucose is broken down into alcohol and carbon dioxide in the absence of oxygen.
Detailed explanation-2: -There are two pathways through which anaerobic respiration occurs. In micro-organisms such as yeast and bacteria, the glucose is broken down into ethanol and carbon dioxide and releases very little energy. In the other pathway, glucose is broken down into only lactic acid with the release of little energy.
Detailed explanation-3: -So, the correct answer is ‘CO2 is given out’.
Detailed explanation-4: -Anaerobic processes do not use oxygen, so the pyruvate product-ATP is one kind of pyruvate-remains in place to be broken down or catalyzed by other reactions, such as what occurs in muscle tissue or in fermentation.
