Answer:
Oxyhemoglobin = Bound. Hemoglobin = Unbound.
Step-by-step explanation:
Oxyhemoglobin and hemoglobin are two forms of protein that carry oxygen in the blood. The primary difference between the two is that oxyhemoglobin is hemoglobin that has bound with oxygen, while hemoglobin is the protein in its unbound form.
Hemoglobin is a protein found in red blood cells responsible for carrying oxygen from the lungs to the body's tissues. When hemoglobin binds with oxygen, it forms oxyhemoglobin, which is bright red. Oxyhemoglobin is the form of hemoglobin that is transported in the bloodstream and delivers oxygen to the tissues that need it.
When oxygen is released from oxyhemoglobin in the tissues, the hemoglobin returns to its unbound form or deoxygenated hemoglobin. Deoxygenated hemoglobin has a darker, bluish color and is transported back to the lungs, picking up more oxygen to form oxyhemoglobin once again.
