Answer:
Observe the graphic for the answer
Explanation:
1.- The first channel from left to right is the pump that exports protons, as you can observe, there are plenty of protons in the outside part, so the cell need to balance the quantity, that is the reason to be of a pump.
2.- The channel in the middle is the responsible for moving calcium, the same as the protons, from the outside part to the inside of the cell.
3.- The lactose carrier, that is the last channel, since the lactose is a carbohydrate that is quite big, needs a protein as a carrier to move it from the outside part to the inside, actually, some carriers can modify it shape as we can observe in the drawing to get inside some substances.

Muscles which are responsible for the movement of the eyeball have fast fibers. Thus, the correct option is A.
<h3>What are fast muscle fibers?</h3>
Fast-twitch muscle fibers are the muscle fibers which provide bigger and more powerful forces, however for shorter durations and fatigue quickly. They are more anaerobic with less blood supply, and hence are sometimes also referred to as white fibers or type II fibers.
Fast-twitch muscle fibers are activated by the high intensity movements which are sustained in short bursts. Examples of movements include sprints, burpees, and quick lateral movements.
Therefore, the correct option is A.
