Question

Cells make use of H+ electrochemical gradients in many ways. Which of the following proton transporters is used to regulate pH in animal cells?

(a) light-driven pump
(b) H+ ATPase
(c) H+ symporter
(d) Na+-H+ exchanger

Answer 1

The Na+-H+ exchanger is used to regulate pH in animal cells.

Step-by-step explanation:

In animal cells, the Na+-H+ exchanger is used to regulate pH. This transporter moves sodium ions out of the cell while moving hydrogen ions into the cell, thereby regulating the pH by removing excess protons.

The Na+-H+ exchanger helps maintain the acid-base balance and pH homeostasis in animal cells.
