Question

In order to pump hydrogen ions across the inner mitochondrial matrix against concentration gradient, energy is needed. If we relate this to transport in the cell membrane across the phospholipid bilayer, it would most be like
active transport.
diffusion.
facilitated diffusion.
passive transport.

Answer 1

Because it requires energy It's active transport 

Answer 2

Answer:

active transport

Explanation:

This type of transport is active transport because it needs energy  to move a substance against its concentration gradient. , to carry out the process consumes chemical energy, such as that derived from adenosine triphosphate (ATP). The cells occupy much of the energy obtained in the metabolism to keep active transport processes running.
