Summary Introduction
Introduction:
Hemoglobin refers to an iron consisting oxygen-carrying metalloprotein present in the RBCs (red blood cells) of almost all the vertebrate and some invertebrates. This is responsible for carrying the O2 (oxygen) from the lungs to the rest of the parts of the body. In tissues, it releases the oxygen, which allows the aerobic respiration to occur in order to supply energy to power the functions of the organism and this process is known as
