Question

What is the molecular composition of hemoglobin? Does the functionality of hemoglobin as a protein depend on its tertiary or quaternary structure?

Answer 1

Hemoglobin consist of 2 imp group i.e., heme and gloubin . hemoglobin is a globular protein with an embdded in heme group. each heme contains 1 iron atom , that can binds one oxygen molecule through ion-induced dipole forces.

yes, the functionality of hemolgobin as a protien depend on its tstructure

tertiary structure- its to decribe how each globin bens in space . the heme molocule is important for the tertiary bending structure of hemogloubin, as it helps to twist the globins into shape by connecting to histidine residues on them

Quaternary structure -the4 gloubin make up hemogloubin,2 are identical and called alpha chains and remaining 2 are beta chains these are also identical the quatenary structure of hemogloubin is these units fitting together.
