Question

A scientist is examining the function of macromolecules in a cell. She notices that movement of large molecules into and out of the cell is disrupted when she damages one specific type of macromolecule.

Answer 1

Answer:

Proteins travel through a membrane via a channel. These channels only allow specific molecule to pass through. Since after the cell was damaged she noticed that the movement of large molecules stopped leads us to the conclusion that proteins are the most likely culprit. I think the macromolecule is protein.
