Based on the provided table about plasma proteins: 1. What protein maintains osmotic pressure? 2. What protein plays a key role in blood coagulation? 3. What protein transport lipids and fat-soluble vitamins? 4. What protein constitutes the antibodies of immunity?

Answer

1. Albumins help maintain colloid osmotic pressure. According to the table, they make up 60% of total plasma proteins and are produced in the liver. 2. Fibrinogen plays a key role in blood coagulation (clotting). Keeping with the table, it accounts for 4% of total plasma proteins and is synthesized in the liver. 3. Alpha globulins and Beta globulins transport lipids and fat-soluble vitamins. These are subcategories of globulins (which total 36%) and originate in the liver. 4. Gamma globulins constitute the antibodies of immunity. Unlike most other plasma proteins, they originate in lymphatic tissues.
