Chapter 01

1) The subcellular structure that degrades proteins is called the:

A. Tight junction
B. Mitochondria
C. Lysosome
D. Plasma membrane
E. Ribosome
ANS: C

2) An experiment is done to measure the uptake of an amino acid into a cell. The following data are
obtained:




If Na+ is removed from the extracellular bathing solution, or if a drug is added that prevents the cell from
making adenosine triphosphate (ATP), the uptake of amino acid into the cell is markedly reduced.
According to this information, which of the followingmechanisms is probably responsible for the
transport of the amino acid into the cell?

A. Passive diffusion through the lipid bilayer
B. Uniporter
C. Transport ATPase
D. Na+ symporter
E. Na+ antiporter
ANS: D

3) A membrane permeable by only Na+ separates two compartments containing
Na2SO4,shown as follows:

Electrodes are placed in both compartments, and a voltage is applied (that of compartment A is held at
0 mV). What voltage applied to compartment B would resultin no net movement of Na+ across the
membrane separating the compartments?

A. –60 mV

K+ 120 mEq/L 4 mEq/L


The cell is treated with a drug to inhibit the Na+,K+-ATPase. What would be the effect ofthis drug on the
following parameters?

Intracellular [Na+] Intracellular [K+] Cell Volume Membrane Voltage
A. Decrease Decrease Decrease Depolarize
B. Increase Decrease Increase Depolarize
C. Increase Increase Increase No change
D. Decrease Increase Decrease Hyperpolarize
E. Increase Increase Decrease Hyperpolarize

6) Which of the labeled proteins (shaded) is attached to the membrane by a
glycosylphosphatidylinositol (GPI) anchor?




ANS: E



7) A cell has channels for Na+, K+, and Cl– in its plasma membrane. The resting membrane
potential is –60 mV (cell interior negative). The intracellular and extracellular
concentrations for these ions, as well as the calculated Nernst potentials, are listed as
follows:
