Detailed explanation-1: -The lactic acid that is produced as a waste product of anaerobic respiration in humans is usually broken down once more oxygen is available. The process of lactic acid breakdown requires oxygen and produces the same products as aerobic respiration, carbon dioxide and water.

Detailed explanation-2: -Lactic acid is the waste product produced during anaerobic respiration. Running fast can lead to a build-up of lactic acid in your muscles, causing cramp.

Detailed explanation-3: -Lactic Acid Fermentation It starts along the same pathway as aerobic respiration, but once glucose is converted to pyruvate proceeds down one of two pathways and produces only two molecules of ATP from each molecule of glucose. In the homolactic pathway, it produces lactic acid as waste.

Detailed explanation-4: -Biogas is generated during anaerobic digestion when microorganisms break down (eat) organic materials in the absence of air (or oxygen). Biogas is mostly methane (CH4) and carbon dioxide (CO2), with very small amounts of water vapor and other gases.

Detailed explanation-5: -The lactic acid system is an anaerobic ener-gy system in which the high-energy compound adenosintriphosphate (ATP) is manufactured from the breakdown of glucose to pyruvic acid in the muscle cells.
