Proteins can buffer a drop in pH with their ___________ side groups and can buffer an increase in pH with their __________ side groups.

Question

Quizplus · Accepted Answer

The side group of amino acid that contains an NH2 is called the amine side group, and it can accept a hydrogen ion or a proton when the pH decreases, giving it the ability to buffer a drop in pH. The side group of amino acid that contains a COOH is called the carboxyl side group, and it can lose a hydrogen ion or a proton when the pH increases, giving it the ability to buffer an increase in pH. Therefore, only option C contains the correct side group answers for both scenarios.
