Ascientist 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. which macromolecule has she most likely damaged?
(a) a carbohydrate
(b) a steroid
(c) a nucleic acid
(d) a protein

(D) a protein

Explanation:

The plasma membrane has proteins that are macromolecules responsible for the movement of large molecules in and out of the cell. If these proteins are damaged, this movement will be stopped.

In addition to acting preferentially on the transport mechanisms, organizing true tunnels that allow substances to pass into and out of the cell, these proteins function as membrane receptors, charged with receiving signals from substances that carry some message to the cell, favor the Adhesion of adjacent cells in a tissue, moreover, serve as the anchor point for the cytoskeleton.

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.
