tertiary and quaternary structure of proteins

what is the tertiary structure?

the overall 3 d shape of a polypeptide chain

where is haemoglobin found?

in red blood cells

what does haemoglobin consist of, and forming what?

haemoglobin consists of four polypeptide chains forming a large molecule

what are the polypeptides which haemoglobin consists of referred to as?

subunits

what does the quaternary structure show?

shows how the individual subunits are arranged to form a larger 3d structure

quaternary structure only applies to proteins with how many subuints?

proteins with at least 2 subunits

what are prosthetic groups?

non protein molecules which form part of the structure

how do prosthetic groups help proteins?

help proteins carry out their role

what prosthetic group does haemoglobin contain, which binds to what?

the prosthetic group haem which binds to oxygen

what are proteins with a prosthetic group called?
