Question

The addition of which of the following to a culture medium will neutralize acids?

A) sugars
B) carbon
C) pH
D) heat
E) buffers

Answer 1

The bicarbonate buffer system in the human body is an example of a buffer that helps maintain blood pH.

Step-by-step explanation:

Buffers absorb excess hydrogen and hydroxide ions to prevent increases or decreases in pH. For example, the bicarbonate buffer system in the human body helps maintain the pH of blood. When excess hydrogen ions are present, bicarbonate ions combine with them to form carbonic acid, thus moderating the pH increase.
