Question

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?

Answer 1

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!).
