Solution

The compound formed by the combination of haemoglobin and carbon dioxide is Carbaminohaemoglobin.

Explanation:

When carbon dioxide (CO2) enters the bloodstream, it binds to the amino groups of the globin proteins in hemoglobin to form carbaminohemoglobin. This is a reversible bond, allowing hemoglobin to safely transport about 20-23% CO2 is released and exhaled, making way for oxygen to bind again.
