Mice from a certain lab strain remain healthy as long as you
feed them regularly and do not let them exercise. After they eat,
their blood glucose level rises slightly and then declines to a
homeostatic level. However if these mice fast or if they exercise
at all, their blood glucose drops dangerously. Which hypothesis
best explains their problem?
a) The mice have insulin-dependent diabetes
b) the mice lack insulin receptors on their cells
c) the mice lack glucagon receptors on their cells
d) The mice can't synthesize glycogen from glucose -
CORRECT ANSWER The mice lack glucagon receptors on
their cells
Liver cells produce glycogen in response to:
a) glucagon
b) insulin - CORRECT ANSWER -insulin
One of insulin's mechanisms of action is to:
,a) activate Na+/K+ pump
b) increase the activity of SGLT
c) increase the facilitated diffusion of glucose into certain cells
in the body
d) increase the number of sodium-linked glucose transporters in
the cell membrane
e) more than one of the above is correct - CORRECT ANSWER
-increase the facilitated diffusion of glucose into certain cells
in the body
NADH is produced from each reaction described except one.
Identify the
EXCEPTION.
a) during "aerobic" glycolysis
b) during the electron transport chain
c) in the Krebs cycle
d) during the conversion of pyruvate to acetyl CoA
e) more than one answer applies - CORRECT ANSWER -
during the electron transport chain
Under low oxygen conditions, ____________ must unload its
electrons to allow glycolysis to continue its production of ATP:
a) FADH2
b) lactic acid
,c) NAD+
d) pyruvate
e) NADH - CORRECT ANSWER -NADH
Which of the following statements about anaerobic metabolism
is FALSE?
a) oxygen is limited or absent
b) pyruvate moves into the mitochondrion but then accumulates
there, since the
Krebs cycle does not occur
c) most of the energy of the glucose molecule remains in the
chemical bonds of the carbon molecule
d) the electron transport chain does not occur since oxygen is
needed as the final electron acceptor - CORRECT ANSWER
-pyruvate moves into the mitochondrion but then
accumulates there, since the Krebs cycle does not occur
From which of the following will the cell be able to harvest the
most chemical energy?
a) an NADH molecule
b) six carbon dioxide molecules
c) two pyruvate molecules
d) a lactic acid molecule
e) a glucose molecule - CORRECT ANSWER -a glucose
molecule
, Which of the following is NOT true of the cell
membrane a) Cholesterol influences how fluid
the membrane is
b) Carbohydrates associate with proteins and lipids on the
extracellular side of the membrane
c) there are many different kinds of membrane proteins
d) in certain cells, the phospholipids arrange themselves into
the shape of a channel, in order to allow ions to transport
across the membrane - CORRECT ANSWER -in certain
cells, the phospholipids arrange themselves into the shape of
a channel, in order to allow ions to transport across the
membrane
The isolation of different proteins to the luminal vs. basolateral
surfaces of epithelial cells is due to the presence of
____________ between the cells in the tissue
a) desmosomes
b) a pump
c) tight junctions
d) gap junctions - CORRECT ANSWER -tight junctions
the GLUT family of molecules are:
a) channel proteins through which glutamic acid can travel
b) carrier proteins for the facilitated diffusion of glucose
c) channel proteins through which glucose can diffuse
d) secondary active transport carriers, for moving both glucose
and sodium
