Understanding Plasma Proteins

What percentage of plasma proteins do albumins constitute?

• 25-30%

• 70-75%

• 40-45%

• 55-60%

List two functions of albumins in the blood.

• Regulate blood pH levels

• Produce antibodies

• 1. Maintain osmotic pressure; 2. Transport substances in the blood.

• Aid in blood clotting

What are the three types of globulins?

• Alpha globulins, beta globulins, gamma globulins

• zeta globulins

• epsilon globulins

• delta globulins

How do globulins contribute to immunity?

• Globulins primarily transport oxygen in the blood.

• Globulins are responsible for clotting blood.

• Globulins serve as a source of energy for cells.

• Globulins contribute to immunity primarily through the production of antibodies that recognize and neutralize pathogens.

What is the primary role of fibrinogen in the blood?

• To regulate blood pressure.

• To provide nutrients to tissues.

• The primary role of fibrinogen in the blood is to aid in blood clotting.

• To transport oxygen in the blood.

What is the difference between serum and plasma?

• Serum contains more proteins than plasma.

• Serum lacks clotting factors; plasma contains them.

• Plasma is derived from red blood cells; serum is not.

• Serum is used for blood transfusions, while plasma is not.

Which plasma protein is primarily responsible for transporting fatty acids?

• Globulin

• Transferrin

• Fibrinogen

• Albumin

What role do albumins play in osmotic pressure?

• Albumins have no effect on osmotic pressure in the body.

• Albumins decrease osmotic pressure by repelling water from the bloodstream.

• Albumins help maintain osmotic pressure by attracting water into the bloodstream.

• Albumins are primarily responsible for transporting oxygen in the blood.

How do α, β, and γ globulins differ in function?

• α globulins are enzymes, β globulins transport hormones, and γ globulins are structural proteins.

• α globulins are antibodies, β globulins transport lipids, and γ globulins transport iron.

• α globulins transport iron, β globulins are antibodies, and γ globulins transport lipids.

• α globulins transport lipids, β globulins transport iron, and γ globulins are antibodies.

What is the significance of bilirubin transport by albumins?

• Bilirubin is transported by albumins to enhance its toxicity.

• Bilirubin transport by albumins is significant for solubilizing bilirubin for safe transport to the liver, preventing toxicity.

• Albumins degrade bilirubin to prevent its accumulation.

• Bilirubin transport by albumins is unnecessary for liver function.
