Detailed explanation-1: -The anaerobic energy system (also called the lactic acid system) is the body’s way of creating energy in the form of ATP quickly. Primarily using glucose as fuel, this energy system powers the muscles anywhere from ten to thirty seconds for intense efforts.
Detailed explanation-2: -However, lactic acid build-up can harm a cell: it reduces the pH, which affects enzymes and other cellular processes. Therefore anaerobic respiration cannot be used for a prolonged period of time without having damaging effects on a cell.
Detailed explanation-3: -Anaerobic respiration happens in muscles during hard exercise. Glucose is not completely broken down, so less energy is released than during aerobic respiration. There is a build-up of lactic acid in the muscles during vigorous exercise. The lactic acid needs to be oxidised to carbon dioxide and water later.
Detailed explanation-4: -So, the correct answer is ‘CO2 is given out’.
