What are the functions of carrier proteins?

Posted January 22, 2024


Functions of carrier proteins include: 

  • Active transport, which requires energy often derived from ATP.
  • Facilitated diffusion, in which molecules are transported down the concentration gradient without energy input
  • Selective permeability, in which carrier proteins regulate the passage of specific substances, maintaining internal cellular environments
