Question

The binding of one o2 molecule to hemoglobin makes it easier for additional o2 molecules to bind. True or False

Answer 1

True

Step-by-step explanation:

Hemoglobin is the channel through which oxygen is transported in the blood. An hemoglobin molecule has the ability to carry four oxygen molecules. These molecules of oxygen bind to the iron of the heme prosthetic group.

When an hemoglobin molecule has no bound oxygen, it assumes the unbound shape. The binding of the first oxygen molecule induces change in the shape of the hemoglobin that increases its ability to bind to the other three oxygen molecules.
