Discuss why a doctor would prescribe an ACE inhibitor to a patient with a history of high blood
pressure. What will be an ideal response?
Concepts to Consider: ACE is an enzyme in the renin-angiotensin-aldosterone pathway. This enzyme
is produced in the pulmonary capillaries and converts angiotensin I into the active form angiotensin II.
Stimulation of this pathway results in aldosterone release, which results in increased reabsorption of
sodium. ADH is also produced, which causes water reabsorption and consequently an increase in
blood pressure as water enters the circulation to maintain osmotic balance. An ACE inhibitor would
block these effects and help to keep blood pressure at a lower value.

In regard to the baby's colorblindness, a sex-linked recessive trait, you explain that
A) colorblindness often appears randomly, even if neither parent is colorblind. B) the baby's father must have a recessive allele for colorblindness. C) since colorblindness is sex-linked, a son can inherit colorblindness if his mother has the recessive colorblindness allele. D) the eggs must have been accidentally switched, since males inherit sex-linked traits only from their fathers.
