BIOS 251 COMPREHENSIVE EXAMINATION
TEST VERIFIED QUESTIONS AND
ACCURATE ANSWERS
●● Primary active transport involves one substance moving down its
concentration gradient to move another substance against its
electrochemical gradient.
True
False
Answer: False
●● A protein transporter which moves two substances by secondary
active transport in the same direction is known as a
symporter
transponder
antiporter
inductor
Answer: symporter
●● Endocytosis is the inward movement of a large particle into the cell
by means of vesicular transport.
,True
False
Answer: True
●● The transport of amino acids into the cell results when sodium ions
move down their electrical gradient and cause amino acids to move into
the cell against their electrochemical gradient. This is an example of
vesicular transport
secondary active transport
simple diffusion
primary active transport
Answer: secondary active transport
●● The process by which a cell produces extensions to engulf a particle
or unwanted cell so it is taken into the attacking cell is known as
pinocytosis
primary active transport
phagocytosis
secondary active transport
Answer: phagocytosis
, ●● When a pouch forms in the cell membrane to enclose extracellular
fluid in a vesicle in order to transport that fluid into the cell, the process
is known as exocytosis.
True
False
Answer: False
●● The movement of one substance into the cell by vesicular transport at
the same rate another substance is moved out of the cell also by
vesicular transport, the process is known as
vesicular reflex
intracellular balance
transcytosis
maintenance of membrane integrity
Answer: trancytosis
●● In order to move calcium ions through the cell membrane, it is
necessary to use the energy in ATP. From what you know about active
membrane transport, which type of transport is involved?
secondary active transport
