8. Protein Function
Myoglobin vs. Hemoglobin
Multiple Choice
Which protein is the primary oxygen-carrying protein in red blood cells?
A
Transferrin
B
Myoglobin
C
Albumin
D
Hemoglobin
Verified step by step guidance1
Understand the function of each protein listed: Transferrin is involved in iron transport, Myoglobin stores oxygen in muscle cells, Albumin maintains osmotic pressure in blood plasma, and Hemoglobin carries oxygen in red blood cells.
Recall that red blood cells are specialized for oxygen transport throughout the body, which requires a protein that can bind oxygen reversibly and efficiently.
Identify that Hemoglobin is the protein found in red blood cells responsible for binding oxygen molecules and transporting them from the lungs to tissues.
Recognize that Myoglobin, although it binds oxygen, is located in muscle tissue and serves as an oxygen reserve rather than a transporter in blood.
Conclude that Hemoglobin is the primary oxygen-carrying protein in red blood cells based on its location and function.
