A 51-year-old woman has been experiencing signs and symptoms of perimenopause and has sought help from her family physician
A deficiency in estrogen levels has been determined to be a contributing factor. Which of the following phenomena could potentially underlie the woman's health problem?
A)
Sufficient synthesis of estrogen but inadequate vesicle-mediated release
B)
Inadequate synthesis in the rough endoplasmic reticulum of her ovarian cells
C)
Insufficient estrogen production within the smooth endoplasmic reticulum of the relevant cells
D)
A lack of prohormone precursors needed for estrogen synthesis and release
Ans:
C
Feedback:
Steroids such as estrogen are produced in the smooth endoplasmic reticulum. Synthesis and release are not separate processes as in the case of peptide hormones, and prohormones are associated with peptide, polypeptide, and protein hormones.
