• A. Acidic
• B. Basic
• C. Neutral
• D. All the above in equal proportions

Answer 1

Answer: (A)

Acidic

Blood proteins are different types of proteins found in blood plasma. These include majorly albumin, globulin, fibrinogen and other regulatory proteins which function as enzymes or hormones. Albumin alone accounts for 55% of the total blood proteins and is acidic in nature. It creates and maintains osmotic pressure of plasma and also helps in the transport of lipids and steroid hormones. Globulin is slightly basic and accounts for 38% of blood proteins. It participates in immune system. Fibrinogen comprises 7% of blood proteins and help in blood clotting.

Thus, the correct answer is option A.
