An elderly person becomes confused and takes an overdose of a medication designed to block both
cholesterol uptake from the gastrointestinal (GI) tract and cholesterol synthesis by all cells. After 24
hours, the individual is severely hypocholesterolemic. This individual would exhibit a transient lower
level of which type of hormone? - ANSWER: iodothyronines
An elderly person becomes confused and takes an overdose of a medication designed to block both
cholesterol uptake from the GI tract and cholesterol synthesis by all cells. After 24 hours, the
individual is severely hypocholesterolemic. This effect is transient" as the effects of the drug wear off,
hormone levels rebound. Which of the following is most responsible for stability of hormone levels in
this situation? - ANSWER: negative feedback loop
Endocrine diseases are often due to loss of hormone. Which of the following would cause an
endocrine disease that mimicked a protein hormone deficiency without a deficiency in the levels of a
circulating protein hormone? - ANSWER: defective receptor
Hormones act through binding to their receptors. Which of following hormones binds only to a
receptor located on the cell membrane? - ANSWER: catecholamine
Many hormones are synthesized as preprohormones. A mutation in a preprohormone-encoding gene
that changed the amino acid sequence of the signal peptide could result in: - ANSWER: inability of the
hormone to be secreted
Endocrine glands are organs dedicated to making hormones. Some organs make hormones but have
other important functions. An example of such a hormone-producing organ that is not considered a
dedicated endocrine gland is: - ANSWER: the liver
The hypothalamus has an important role in the hypothalamic-pituitary-endocrine gland axes. As part
of these axes, hypothalamic neuroendocrine neurons secrete: - ANSWER: releasing hormones
Many pituitary hormones are secreted in a circadian rhythm. A structure important in the regulation
of circadian hormonal rhythms is: - ANSWER: the suprachiasmatic nucleus
Protein hormones are secreted in a regulated manner, through a mechanism referred to as: -
ANSWER: stimulus-secretion coupling
An important process that can activate a steroid hormone or even change a steroid hormone into a
different type of hormone is called: - ANSWER: peripheral conversion
During his annual physical examination, a 55 year old man is noted to have a body mass index of 33
(>30 indicates obesity) and high blood pressure. His blood chemistry profile indicates
hyperlipidemia...... (super long question) - ANSWER: insulin resistance
High circulating lipid levels are typical of the prediabetic and diabetic states. When the liver is
saturated with glucose from the blood, it converts the glucose into free fatty acids (FFAs) and
triglycerides. One of the enzymes involved in hepatic lipogenesis is: - ANSWER: acetyl coenzyme A
(CoA) carboxylase
Levels of circulating FFAs are often elevated in the prediabetic and diabetic states. This is due to: -
ANSWER: elevated levels of hormone-sensitive lipase
