Gross profit margin is the gross profit $ expressed as a % of the revenue. So, if gross profit is $10,000 and the revenue was $30,000 then the gross profit margin is ... 10,000 divided by 30,000 = 33.33%. This is a measure of the firm's profitability being obtained from it's core activities. Net profit is the $ left over from the gross profit after deducting the overheads. Net profit margin is the net profit $ expressed as a % of the revenue. So, if net profit is $5,000 and the revenue was $30,000 then the net profit margin is ... 5,000 divided by 30,000 = 16.66%.

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 Versus Anaerobic Activities. When you perform short and intense activities that require maximal energy, you rely on your anaerobic metabolism. For example, the energy used to run a 100-meter sprint is about 100 percent anaerobic. The primary nutrient for this type of exercise is carbohydrates.hen a glucose molecule is converted into carbon dioxide and water via aerobic metabolism, it produces 39 molecules of ATP. However, glycolysis requires powerful enzymes that compensate for the lower energy efficiency of anaerobic metabolism.
