Iron Ion Role in Hemoglobin Function by notme is a document available to read on EtoBox.

Transition metal ions play important roles in biological systems. Hemoglobin transports oxygen in the blood via its heme group, which contains an iron ion. Hemoglobin picks up oxygen in the lungs where it binds to the iron, forming oxyhemoglobin. In tissues, oxygen is released from oxyhemoglobin as the iron binds water instead. This process is cooperative, such that when one oxygen is released, it makes the others easier to release as well. The iron can also bind other ligands like carbon monoxide, acting a
