Questions and Answers

Explain why maintenance of acid-base is critical to cell function

Changes in the balance can cause issues with the cardiovascular system, nervous system, respiratory, response to various drug therapies

Explain the relationship between H+ concentration and pH

pH is the concentration of protons in a solution. It has an inverse relationship . The more H+, the lower the pH.

Explain the Henderson-Hasselbalch equation and what can be measured using it.

The equation is used to evaluate the pH using an equilibrium concentrations of the conjugate acid/base pairing of the buffer system
