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:
N
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:
, Berne and Levy Physiology 8th Edition Koeppen
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
B. –30 mV
C. 0 mV
D. +30 mV
E. +60 mV
