Which of the following proteins is found in plasma?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Albumin.
- Albumin protein is found in plasma.
- Plasma proteins are of three different types: albumin, globulins, and fibrinogen.
- Plasma plays a vital role in the body by carrying nutrients, hormones, and proteins to the cells. It also helps remove metabolic waste by transporting it from tissues to organs responsible for detoxification or excretion.
- Plasma is composed mostly of water (about 90%), the remaining 10% also contains ions, dissolved gases, proteins, nutrients, and waste products.
- Albumin, the normal concentration of which is 35–45 grams per liter, makes up about half of the total protein content in plasma.
- Albumin plays a crucial role in maintaining the colloid osmotic pressure of the blood, which helps regulate the fluid balance between blood vessels and surrounding tissues. Though it is the smallest among plasma proteins, albumin makes up the largest proportion of them.
