True or False Iron is necessary for oxygen transport in red blood cells?

True.

Iron is an essential mineral that plays a crucial role in the human body, particularly in oxygen transport. It is a key component of hemoglobin, a protein found in red blood cells that binds to oxygen and transports it throughout the body. Without sufficient iron, the production of hemoglobin is impaired, leading to a condition called iron-deficiency anemia, characterized by a reduced ability of the blood to carry oxygen to tissues.
