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

Proteins are the macromolecules damaged by the scientists while performing experiment.

Explanation:

Lipids and proteins are two components that makes the cell membrane and help them to play their role. Proteins found in between the bilayer of lipids and assists the bilayer transferring of various substances in and out of the cell also known as carrier molecules.

Hence, when scientist was examining the macromolecules, the proteins were get damaged and thus the movement of materials also get interrupted.

Thus, to the given question protein is the answer.

i think that d. wind is the answer.   i missed the question when i answered a. currents.
