What is the protein that occurs in blood plasma?

• A. Albumin
• B. Angina pectoris
• C. Anemia
• D. Arteriosclerosis

Answer: (A)

Albumin is the protein that occurs in blood plasma. It is the most abundant plasma protein and is produced by the liver. Its main job is to maintain the blood’s oncotic (colloid osmotic) pressure, helping to keep fluid inside the blood vessels and prevent edema. Albumin also acts as a carrier, binding and transporting substances such as fatty acids, hormones, bilirubin, and some drugs. The other terms listed are not plasma proteins—they describe conditions or diseases (chest pain from heart ischemia, a low red blood cell or hemoglobin count, and the hardening of arteries). So albumin fits as the protein present in blood plasma.
