WebIn this case, called allosteric inhibition, binding to this other part of the molecule changes the enzyme in some way that makes it less likely to bind the oxygen. You can imagine that if a big molecule, for instance, were to bind to this "allosteric" site and push on other parts of the enzyme it might change the active site where the oxygen ... WebMar 16, 2024 · Reversible Binding of a Ligand to a Macromolecule Reversible, noncovalent binding of two or molecules is the first step in the expression of the biological properties of almost all biomacromolecules. If one of the molecules is small, it's often called a ligand. Ligands are often referred to by other names.

WebAlmost 30\% 30% of the mass of RBCs is made up by hemoglobin. This allows RBCs to carry much more oxygen than could otherwise be dissolved into blood.
