Question

how hemoglobin reacts​

Answer 1

Answer:

Haemoglobin is a protein that is made up of four haem groups, which contain iron ions. These iron ions (Fe2+) associated with haemoglobin molecules chemically react with oxygen to form oxyhaemoglobin. Each molecule of haemoglobin can hold four oxygen molecules.

Red blood cells and haemoglobin

The red blood cells contain a pigment called haemoglobin, each molecule of which binds four oxygen molecules. Oxyhaemoglobin forms. The oxygen molecules are carried to individual cells in the body tissue where they are released.
