NPB 101 FINAL QUESTIONS & ANSWERS
The enzyme carbonic anhydrase facilitates - Answers -The increased carrying capacity
for CO2 in the blood
The chemical digestion of fats begins in - Answers -The duodenum
Which of the following inputs will result in increased release of GHRH? - Answers -
Exercise
Intrinsic control of arteriole radius includes - Answers -vasoconstriction due to
increased oxygen concentration
The basal electrical rhythm of the intestine is generated by - Answers -The membrane
potential of interstitial cells of Cahal
For his thesis research, Karl creates a mutant mouse that does not make the hormone
GIP. We expect
this mouse will exhibit - Answers -Impaired/reduced insulin secretion after ingestion of
oral glucose (drinking a sugary drink)
Two diseases/symptoms of a dysfunctional basal ganglion are - Answers -Huntington's
Chorea and Parkinson's
Imagine you are a scientist working to produce a hormonally-based contraceptive for
use by women,
which of the following hormones could be effective (ignoring side-effects). - Answers -
Progesterone and testosterone
Which of the following best describes a critical role of the Type II alveolar cells -
Answers -Secretes surfactant
A typical neuron can maintain its shape due to the - Answers -microfilaments
The part of the cell that provides the necessary energy to transport molecules long
distances, like
vesicle-associated proteins from the cell body to the synapse, is the - Answers -
mitochondria
If you ingest a poison that blocks half of your voltage-gated Na+ channels but does not
cross the
blood brain barrier, the consequence would be - Answers -anxiety and fear due to your
difficulty moving and breathing
, Imagine that you are constructing contractile cells in the heart. If you replace the
voltage-gated K+
channels that are normally in these cells with the voltage-gated K+ channels normally
found in
neurons, the result would be - Answers -a shortened plateau phase
The neuromuscular junction of skeletal muscle - Answers -is a synapse where the
neuron releases acetylcholine onto the muscle cell
The reason that you can be a quadriplegic (paralyzed arms and legs) and yet still breath
on your
own is because the diaphragm is innervated by the lower cervical segments of the
spinal cord, not the
ones that innervate the chest. However, these patients will still have general
physiological troubles
because - Answers -the axons from the cardiovascular center that control of the
sympathetic nervous system are
lesioned
The autonomic nervous system has two divisions, the sympathetic and
parasympathetic. Major
differences between these two include - Answers -the neurotransmitter that is released
and the length of the post-ganglionic neurons
Scout has very high blood concentrations of growth hormone. Of the following potential
treatments, which might be effective to slow/stop Scout's growth? - Answers -Estrogen
Jeremy is being chased across the savannah by a lion, and this activates his integrated
response to
stress. Based on what you've learned in this course, which of the following statements is
true: - Answers -Increased activity of the sympathetic nervous system leads to
increased heart rate, decreased
secretion from the exocrine pancreas, and decreased resistance to airflow in the
bronchioles
A major physiological role of the hormone insulin is - Answers -Stimulates anabolic
reactions and inhibits catabolic reactions to facilitate fuel storage
If it were possible to insert more Na+ transport pumps in the ascending loop of Henle,
the result
would be - Answers -the ability to make more concentrated urine
For a given volume of air exchange, which of the following would require an increase in
the
transmural pressure gradient? - Answers -Decreased secretion from Type II alveolar
cells

for CO2 in the blood
