Answer 1

concentration gradient

Step-by-step explanation:

concentration refer to number of ions on either side of membrane

gradient :difference in concentration on both sides of membrane

on this basis:

one side of membrane: higher concentration of h+ ion

other side of membrane :lower concentration f h+ ions

pumps transport ions from higher concentration side to lower concentration side of membrane
