Final answer:
Most of the body's iron is found in two proteins: hemoglobin and myoglobin.
Step-by-step explanation:
The statement is True.
Most of the body's iron is found in two proteins called hemoglobin and myoglobin. Hemoglobin is found in red blood cells and carries oxygen to cells and carbon dioxide to the lungs, while myoglobin is found in muscle cells and stores oxygen for muscle contraction. Both proteins contain iron ions that bind to oxygen. Hemoglobin is responsible for the red color of blood due to the iron associated with heme groups.
