    Which of the following transporters does not use passive transport to move molecules across a membrane?
    A) GLUT-1 glucose transporter
    B) Sodium–potassium pump
    C) Valinomycin
    D) Gramicidin ion channel?
    Sodium-potassium pump

    This pump uses the energy provided by ATP hydrolysis to transport sodium and potassium ions across the membrane.

    when molecule travels from a higher concentration to a lower concentration through a concentration gradient.It is known as passive transport.
  • garydfreeman
    ______ refers to when molecule travels from a region of lower concentration to a region of higher concentration against the concentration gradient.

    A) Active Transport
    B) Passive Transport
    C) Diffusion
    Active Transport

  • garydfreeman
    True or false? Active transport differs from passive transport in that active transport does not require an input of energy.
    False

    Active Transport requires the cells' own use of energy (ATP)

    Which membrane protein would be used to move glucose across a membrane from a region of higher concentration to a region of lower concentration?

    A) Pump
    B) Ion channel
    C) Transporter
    D) No protein is necessary.
    Transporter

    The GLUT-1 transporter assists the diffusion of glucose through the membrane.

    Which of the following statements is true about the net movement of an ion across a membrane by passive diffusion through a membrane channel?

    The charge on the other side of the membrane is generally the opposite of the ion's charge.
    b) The cell expends energy as the ion passes through the membrane.
    c) For every ion that diffuses through the membrane, a different ion diffuses in the opposite direction.
    d) There is a higher concentration of ions on the side of the membrane toward which the ion diffuses.
