OP

Which process takes place if the hydrogen ions move without the help of

additional energy?

O

A. Simple diffusion

O

B. Reverse osmosis

O

c. Active transport

O

D. Facilitated diffusion

Answer 1

Facilitated diffusion.

Step-by-step explanation:

Facilitated diffusion is a process in which an ion moves from one side to the other of the membrane without additional energy because it is moving in favor of the electrochemical gradient . For this diffusion a specific ion channel for the hydrogen ion in the membrane of the cell is needed.
