An excess one of the components of hemoglobin decreases tbc survival
Explanation;
-Each hemoglobin molecule is made up of four heme groups surrounding a globin group, forming a tetrahedral structure. Heme, which accounts for only 4 percent of the weight of the molecule, is composed of a ringlike organic compound known as a porphyrin to which an iron atom is attached.
-Heme is synthesized in a complex series of steps involving enzymes in the mitochondrion and in the cytosol of the cell. Two distinct globin chains (each with its individual heme molecule) combine to form hemoglobin. One of the chains is designated alpha. The second chain is called non-alpha.
