Q. 2 - Biology

Question

Figure 43.15  Which of the following statements about hormone regulation of the female reproductive cycle is false? a. LH and FSH are produced in the pituitary, and estradiol and progesterone are produced in the ovaries. b. Estradiol and progesterone secreted from the corpus luteum cause the endometrium to thicken. c. Both progesterone and estradiol are produced by the follicles. d. Secretion of GnRH by the hypothalamus is inhibited by low levels of estradiol but stimulated by high levels of estradiol 

Step-by-Step Solution

Answer

The False statment  is C. Both progesterone and estradiol are produced by the follicles. 

Step 1. Given infromation

Gonadotropin-releasing hormone (GnRH) to the anterior pituitary. 

This causes the release of follicle stimulating hormone (FSH) and luteinizing hormone (LH) 

Step 2. Explanation

The false statemen is  option c Both progesterone and estradiol are produced by the follicles.  

  because induction of ovulation, and stimulation of estradiol and progesterone production by the ovaries. Estradiol and progesterone are steroid hormones that prepare the body for pregnancy. Estradiol produces secondary sex characteristics in females, while both estradiol and progesterone regulate the menstrual cycle.
