This is an interesting and very open-ended question.
By transport mechanism within a cell, I assume you are referring to how a cell takes molecules from point A to point B.
Well, the answer is ...
Cytoskeleton, vesicles, and motor proteins!
Remember, your cytoskeleton is composed of protein that is shaped into long shapes that span across a cell, kind of like a railroad. A vesicle is a spherical object protected by a layer of phospholipids. A motor protein attaches the vesicle to the cytoskeleton and provides the energy to move the vesicle to where it is supposed to go.
A simple analogy:
Vesicle = train carriage
Cytoskeleton = railroad
Motor protein = engine
If this transport mechanism is disrupted, all sorts of things can go wrong. The easiest example to think about is a neuron. A neuron is an extremely long cell that relies on this transport mechanism from sending neurotransmitters from one end of the cell ALL THE WAY down to the other end.
If this is disrupted in a neuron, do you think you would a person will feel any changes to their nervous system? Would they be able to feel certain sensations as they used to before this transport mechanism was disrupted?
