If adenylyl cyclase (the enzyme that converts ATP to cAMP) is blocked,
◦ the activity of progesterone at the endometrium would increase.
◦ the corpus luteum would not respond to hCG.
◦ the mammary glands would not respond to progesterone.
◦ endometrial cells would not respond to estradiol.
◦ the level of progesterone produced by the ovary during the luteal phase would increase.
