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.
Aerobic metabolism is a physiological process that requires oxygen to be available in order to use carbohydrate, fat, or protein for energy production. When oxygen is not available, only carbohydrate can be used for energy, this is anaerobic metabolism.You use primarily aerobic metabolism for energy when you are working at a low to moderate pace during exercise. Walking briskly, cycling at approximately 12 mph, or a light to moderate jog would be good examples.hen oxygen is not available, only carbohydrate can be used for energy, this is anaerobic metabolism. You use primarily aerobic metabolism for energy when you are working at a low to moderate pace during exercise.
