D
Albumin
Verified step by step guidance1
Understand the function of each protein listed: Hemoglobin, Cytochrome c, Myoglobin, and Albumin.
Recall that hemoglobin is a red, iron-containing protein found in red blood cells responsible for transporting oxygen from the lungs to tissues throughout the body.
Recognize that myoglobin is also a red, oxygen-binding protein but is found primarily in muscle tissue, serving as an oxygen storage molecule rather than a transporter in blood.
Note that cytochrome c is involved in electron transport within mitochondria and is not related to oxygen transport in blood.
Understand that albumin is a major plasma protein involved in maintaining osmotic pressure and transporting various substances, but it does not transport oxygen.
