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%. This is a measure of the firm's overall profitability, performance and sustainability.
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.
When one glucose molecule is converted into lactic acid in anaerobic metabolism, three ATP molecules are generated. When 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. What limits the anaerobic process is the byproduct, or lactic acid.n the case of anaerobic metabolism, pyruvate enters the fluid, or cytoplasm, of the cell and is turned into lactic acid via a process called glycolysis. While aerobic metabolism uses fat, protein and carbohydrates and can continue indefinitely, anaerobic metabolism uses only carbohydrates and doesnât last long.
