Final answer:
Hemoglobin is a protein found in red blood cells that binds and transports oxygen, while myoglobin is a protein found in muscle tissue that binds and stores oxygen.
Step-by-step explanation:
Hemoglobin is a protein found in red blood cells that binds and transports oxygen throughout the body, while myoglobin is a protein found in muscle tissue that binds and stores oxygen.
Hemoglobin contains four iron-containing heme molecules, allowing it to bind up to four molecules of oxygen. This enables it to efficiently transport oxygen from the lungs to the body's tissues.
On the other hand, myoglobin has a higher affinity for oxygen, allowing it to effectively bind and store oxygen within muscle cells. This stored oxygen can be used during periods of increased demand, such as during exercise.
