Questions and Answers

What is a characteristic of carrier-mediated transport that distinguishes it from simple diffusion?

  • Dependence on solute concentration
  • Inability to transport isomers
  • Lack of competition between solutes
  • Involvement of a carrier (correct)

What happens when the carriers in carrier-mediated transport are saturated?

  • The transport rate increases
  • The transport rate becomes unpredictable
  • The transport rate decreases
  • The transport rate remains constant (correct)

What does the transport maximum (Tm) in carrier-mediated transport refer to?

  • The maximum number of carriers
  • The maximum concentration of the solute
  • The maximum velocity of transport (correct)
  • The maximum time for transport
