Detailed explanation-1: -The cell membrane is the outer layer of the cell. The primary function of the cell membrane is to regulate what substances enter and leave the cell. The cell membrane is selectively permeable, or “semi-permeable", meaning that the membrane only allows certain substances to enter or leave the cell.

Detailed explanation-2: -Cationic amino acids can enter cells through uniporters, such as CAT1, or through antiporters, such as y+LAT2, which exchanges a neutral amino acid together with Na+ or K+ against a cationic amino acid14.
