View Mr C Biology Respiration PNG. Revise how the human respiratory system is adapted to allow air to pass in and out of the body, and for efficient gas exchange to happen. Cell respiration involves the oxidation and reduction of electron carriers.
Respiratory substrates are those organic substances which are oxidised during respiration 6. External respiration, demonstrating the difference between a normal and an obstructed airway. Revise how the human respiratory system is adapted to allow air to pass in and out of the body, and for efficient gas exchange to happen.
It is a simple process of exchange of gases (o2 and co2) between the respiratory surface and the environment.
Respiration is a set of metabolic reactions and processes that take place with in the cells of organisms. What are the main steps in aerobic respiration? External respiration is when your blood exchanges gasses with the air in the lungs' alvioli. Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into atp, and then release waste products.
