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.
Use of ATP usually does not lead to a decrease in ATP levels, due to the very rapid resynthesis. Extreme muscle activity leads to no more than a 20% reduction in ATP concentration in muscles. Only carbohydrates (glycogen or blood sugar) can be used anaerobically.Neither amino acids nor fatty acids can be processed without use of oxygen. Muscles differ in their ability to produce ATP through anaerobic and aerobic reactions. Fast-twitch white muscles with few mitochondria are the anaerobic fibers.nergy production, that is ATP synthesis from ADP and Pi, can occur anaerobically (without the use of oxygen) or aerobically (using mitochondrial reactions and oxygen). These reactions, especially anaerobic metabolism, are quite rapid.
