Anaerobic digestion is a process through which bacteria break down organic matterâsuch as manureâwithout oxygen. As the bacteria âwork,â they generate biogas. The biogas that is generated is made mostly of methane, the primary component of natural gas. The non-methane components of the biogas are removed so the methane can be used as an energy source.
Anaerobic respiration. Not enough oxygen may reach the muscles during exercise. When this happens, they use anaerobic respiration to obtain energy. Anaerobic respiration involves the incomplete breakdown of glucose.It releases around 5% of the energy released by aerobic respiration, per molecule of glucose glucose: A simple sugar made by the body from food, which is used by cells to make energy in respiration.naerobic respiration produces an oxygen debt. This is the amount of oxygen needed to oxidise oxidation: Oxidation is a reaction in which oxygen combines with a substance. Oxidation also means a loss of electrons. lactic acid to carbon dioxide and water.
