a scientist is examining the function of macromolecules in a cell. she notices that movement of large molecules into and out of cell is disrupted when she dameges one specific type of maromolecule. which macromolecule has she most likely damaged?
Likely she's disrupted a transport protein - transporter is another name that's used. These are membrane-bound proteins that open and close to let molecules into and out of the cell. They are specific for a molecule (not one size fits all!).
