Answer:
The movement of proteins and enzymes within a cell is facilitated by intracellular receptors.
Explanation:
Proteins and enzymes (which also are proteins) move inside the cell through intracellular receptors. These receptors are proteins capable of binding other molecules such as proteins and hormones in order to transport them to different cellular locations. Thus, intracellular receptors are key players in signaling pathways that trigger signaling events to regulate a particular function, for example, activating gene expression by transporting proteins to the nucleus.

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.
