What give color red in the blood

Sagot :

Blood is red because it is made up of cells that are red, which are called red blood cells. Within the red blood cells there is a protein called hemoglobin. Each hemoglobin protein is made up subunits called hemes, which are what give blood its red color. More specifically, the hemes can bind iron molecules, and these iron molecules bind oxygen.
the one that gives color to the blood is HEMOGLOBIN
