Hemoglobin is a protein that
A
transports oxygen in the blood
B
makes sugar
C
breaks down fats
D
builds muscles
Explanation: 

Detailed explanation-1: -Hemoglobin (Heme + Globin) The protein hemoglobin is a molecule which is responsible for carrying almost all of the oxygen in the blood. It is composed of four subunits, each with a heme group plus a globin chain. The heme group is composed of a porphyrin ring which contains an iron (Fe) atom in its center.

Detailed explanation-2: -Hemoglobin contains iron, which allows it to pick up oxygen from the air we breathe and deliver it everywhere in the body. You can think of hemoglobin as the iron ("heme"), oxygen transport protein, ("globin") found in red blood cells.

Detailed explanation-3: -Hemoglobin and myoglobin both are the transport proteins, Hemoglobin transportation:-It carries oxygen from the lungs to the rest of the body and a portion of carbon dioxide in the opposite direction.

Detailed explanation-4: -Hemoglobin is a protein found in red blood cells. It contains iron, which allows it to transport oxygen. Each hemoglobin molecule can bind up to four oxygen molecules. This way, it can transport the oxygen from the lungs to the tissues that need it.

Detailed explanation-5: -Oxygen is one of the substances transported with the assistance of red blood cells. 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.
