enzymes are a biological catalyst that act on molecules called substrates and converts the substrates into different molecules known as products.
a substrate is the material upon which an enzyme acts, can be lipid, protein or carbohydrates.
active site is the region of an enzyme where the substrate will bind and undergo a chemical reaction.
Answer:
(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.
