collagen = made of two polypeptide chains and has hydrogen bonds present which makes the whole structure strong and is not branched.

Glycogen has moe branched but the 1,4 linked glucose molecules are shorter than starch

Yep, the pressure in the alveoli might build up because of scarring of the elastic tissue around the alveoli, reducing it's elasticity, causing them to burst under the pressure. Yep use all those words, SA:vol. ratio, tiredness, shortness of breath.
specifically, primary immune response is the production of antibodies to combat the infection, secondary response is faster because memory cells are made and enter the blood after primary infection.

what else was in there... how is collagen's structure useful for it's function? how does glycogen differ from starch.
