Yes, all polypeptides have tertiary structures. All proteins have primary, secondary and tertiary structures. However, quaternary structures only arise when a protein is made up of two or more polypeptide chains. Hope this answers the question. Have a nice day.

The right answer is the lysosome
The lysosome is a eukaryotic cell organelle.
The lysosome contains hydrolases, enzymes intended for the degradation of intracellular molecules. They are only active at acidic pH, hence the lowering of the pH in the vesicle.
The lysosome has a cellular garbage function, where the non-functional or undesired molecules are removed by digestion.
The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.
