Buffer systems in the body maintain proper pH balance in order for life processes to proceed. Proteins found in the blood plasma are often used as buffers.
What makes a protein able to function as a buffer?
O The protein's molecular shape must enable it to bind with other proteins in the plasma.
O The protein must be capable of both accepting and releasing protons.
O The protein must maintain its ability to release various amino acids, thus changing its molecular shape.
O The protein must take on a conformation change according to the activity of the associated enzyme in regulating
the blood's pH.
