Detailed explanation-1: -hemoglobin, also spelled haemoglobin, iron-containing protein in the blood of many animals-in the red blood cells (erythrocytes) of vertebrates-that transports oxygen to the tissues. Hemoglobin forms an unstable reversible bond with oxygen.

Detailed explanation-2: -Hemoglobin is the protein that makes blood red. It is composed of four protein chains, two alpha chains and two beta chains, each with a ring-like heme group containing an iron atom. Oxygen binds reversibly to these iron atoms and is transported through blood.

Detailed explanation-3: -Haemoglobin forms an unstable and reversible bond with oxygen. It is referred to as oxyhaemoglobin in the oxygenated state and is bright red in colour and is purplish blue in shade in the reduced state.
