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.
There are two systems within Anaerobic metabolism, which are the ATP-PC system and the lactic acid system. ATP-PC System. ATP as already discussed is a high energy molecule which is broken down to form ADP and release energy.PC or Phosphocreatine is another high energy molecule, found in the Sarcoplasm of muscle fibres.ue to lactic acid production, this energy system can only be predominant for up to 2 minutes. Following anaerobic exercise, despite the metabolic process used not requiring oxygen, your body will be in Oxygen Debt and so your respiration rate will be very high.
