Question

Hemoglobin is made of heme and globin. What are the components of hemoglobin?

1) Heme and globin
2) Heme and oxygen
3) Globin and carbon dioxide
4) Heme and carbon dioxide

Answer 1

Hemoglobin is made up of heme and globin proteins, with each globin being associated with a heme group containing iron that binds oxygen. The correct components of hemoglobin are heme and globin.

Step-by-step explanation:

Components of Hemoglobin

Hemoglobin, which is the protein found inside red blood cells, is responsible for the transport of oxygen to body cells and the removal of carbon dioxide to the lungs. The key components of hemoglobin are heme and globin. Each molecule of hemoglobin is made up of four globin proteins, each associated with a heme group. The heme group contains iron, which is essential for binding oxygen, and it is this iron that gives blood its characteristic red color.

The correct answer to the question "What are the components of hemoglobin?" is 1) Heme and globin. The globin part consists of two alpha and two beta polypeptide chains, while the heme is an iron-porphyrin compound that is embedded within the globin structure. Hemoglobin can bind up to four oxygen molecules, one for each heme group in the protein.
