The amount of air that is moved between the atmosphere and alveoli in 1 minute is . the normal adult breathes approximately ml per breath ( ), and this occurs about times per minute. the amount of air taken in during 1 minute is and is calculated using the following formula: . the amount of air that reaches the alveoli and is available for gas exchange per minute is termed . this is calculated using the following mathematical formula:

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
