WebThe tertiary structure is the further folding of a polypeptide to give a more complex 3D shape. The shape is very precise and specific to the function of the polypeptide. The quaternary structure of a protein is if it is made of two or more polypeptides. Haemoglobin is an example with a quaternary structure because it has four polypeptides. WebTo support the absorption of oxygen and release of carbon dioxide, about 5 to 8 liters (about 1.3 to 2.1 gallons) of air per minute are brought in and out of the lungs, and about three tenths of a liter (about three tenths of a quart) of oxygen is transferred from the alveoli to the blood each minute, even when the person is at rest.
