In humans, the amount of O₂ in the air exhaled during respiration is 16%. Exhaled air contains a lower concentration of oxygen compared to inhaled air because oxygen is absorbed by the body’s tissues during cellular respiration.
As a result of complete oxidation of glucose, 38 molecules of ATP are formed. This process occurs through cellular respiration, which includes glycolysis, the Krebs cycle, and oxidative phosphorylation, producing a large amount of ATP.
A human being typically breathes 20-25 times in a minute. This respiratory rate can vary depending on factors such as age, physical activity, health status, and environmental conditions but generally falls within this range for adults at rest.
The conversion of food into energy takes place in Mitochondria. Mitochondria are organelles responsible for cellular respiration, where glucose and other nutrients are oxidized to produce ATP, the energy currency of the cell.
