Please explain.

Answer 1

Heme is an example of a non-peptide, enzyme-associated cofactor that binds tightly -- often through covalent linkages-- to an enzyme complex. Collectively, such molecules are known as Prosthetic groups.

The Heme gathering enables myoglobin and hemoglobin to tie oxygen due to the nearness of iron. Iron binds tightly to the heme group in the protein hemoglobin. Every heme gathering contains an iron iota that can tie to one oxygen (O2) atom and is the basic part of the hemoglobin protein. prosthetic gathering comprising of a protoporphyrin ring and a focal iron (Fe) molecule. A protoporphyrin ring is comprised of four pyrrole rings connected by methene spans.
