The human body requires cholesterol. It is used to correct answer: d. the cell membrane
construct:
a. muscle fibers Cholesterol is used by the cell to construct the phospholipid bilayer of the cell
b. proteins membrane. Every cell in the body.
c. DNA
d. the cell membrane
Mitochondria contain the enzymes necessary for: correct answer: d. ATP production
a. gluconeogenesis
b. phagocytosis Mitochondria are the powerhouses of the cell. Their main function is to produce
c. photosynthesis ATP.
d. ATP production
The movement of ions through the sodium-potassium correct answer: b. active transport
pump is an example of ________.
a. osmosis The sodium-potassium pump is an example of an active transport pump. Active
b. active transport transport requires an energy input; in this case, ATP.
c. simple diffusion
d. passive transport
In the resting membrane potential, potassium is correct answer: c. intra-; extra-
predominantly an ________-cellular ion and sodium is
predominantly an ________-cellular ion. Sodium in predominantly an extracellular ion, with a normal serum concentration
a. extra-; intra- of 135-145 mEq/L and intracellular concentration of 3.5-5 mEq/L. Potassium is
b. intra-; intra- largely an intracellular ion, at concentrations of 135-145 mEq/L intracellularly and
c. intra-; extra- extracellular concentration of 3.5-5 mEq/L.
d. extra-; extra-
During the action potential of a muscle or nerve cells, correct answer: all or none
sodium rushing into the cell causes an ________ response.
An all-or-none response occurs after sodium influx, which results in the
subsequent phases of the action potential. Once sodium influxes into the cell,
conduction cannot be stopped.
, Hypertension, or high blood pressure, requires the heart correct answer: b. hypertrophy
to become stronger. The cell's adaption strategy in
response to hypertension is ________. Hypertrophy is the equivalent of body builders getting huge from lifting weights.
a. atrophy
b. hypertrophy
c. metaplasia
d. dysplasia
Gangrene is an example of: correct answer: c. necrosis
a. hyperplasia
b. apoptosis
c. necrosis
d. cellular aging
An individual who carries a copy of the gene is a carrier. correct answer: c. heterozygous
A synonym for carrier, in this case, is ________.
a. recessive
b. dominant
c. heterozygous
d. homozygous
Huntington's disease is an autosomal dominant genetic correct answer: d. 100%
disorder. One strange and cruel feature of Huntington's
disease is that patients usually have had children by the Since Huntington's disease follows an autosomal dominant inheritance pattern,
time symptoms emerge. What is the likelihood that any dominant allele (i.e. "big H") that is passed on will result in the disease. In the
children of parents—each homozygous (i.e. HH and HH)— case of two homozygous parents, 100% of the offspring will have the disease.
will inherit the disease?
a. 25%
b. 75%
c. 50%
d. 100%
What is epigenetics? Epigenetics is the study of changes in organisms caused by modification of gene
expression rather than alteration of the genetic code itself.
Antigen-presenting cells function to: correct answer: d. display foreign antigen on their cell surfaces bound to MHC
a. initiate the complement cascade by way of the
alternate pathway
b. stimulate cytokine production by macrophages
c. phagocytose and degrade foreign antigens
d. display foreign antigen on their cell surfaces bound to
MHC
Which clinical finding is most indicative of an acute correct answer: a. increased (band) neutrophils
bacterial infection?
a. increased (band) neutrophils Remember that initially in the stress response (release of cortisol) WBCs are
b. elevated erythrocyte sedimentation rate released from their moorings along the vessel walls. It takes time for more WBCs
c. elevated WBC count to be produced in the bone marrow and the first WBCs to be released are
d. elevated temperature immature "teenagers" who haven't yet matured into fully functional neutrophils.
THAT's the indication that there's an active infection. We call it a "left shift;" a shift
to less mature cells in response to active infection.
