Question

Which of the following are steroid hormones?

a. cholesterol

b. cortisol

c. estradiol

d. testosterone

Step-by-Step Solution

Answer

The adrenal medulla manufactures cortisol, an endocrine protein. So, the correct choice is (part b), (part c) and (part d).

Step 1: Introduction (part a)

Steroids lack a fatty acid group or have a steroidal nucleus. This steroidal center is made up of three six-membered rings and a five-membered ring united combined.

Step 2: Given Information (part a)

Cholesterol, steroidal chemicals like oestrogen (estradiol), progesterone, testosterone, and corticosteroidal.

Step 3: Explanation of Incorrect Answer (part a)

Cholesterol is just not a receptor, it is instead a triterpenoids component. It is an injectable testosterone estrogen transporter and then an essential component of the organism.

Option (a) thus is incorrect.

Step 4: Given Information (part b)

(part b) The adrenal medulla manufactures cortisol, an endocrine protein. 

Step 5: Explanation of Correct answer (part b)

The endogenous hormones estradiol and testosterone are controlled by hormones and genitals, accordingly.

As a conclusion, the choices were indeed:  (b) cortisol

Step 6: Given Information (part c)

(part c)  steroid hormones - estradiol 

Step 6: Explanation of Correct Answer (part c)

The endogenous hormones estradiol and testosterone are controlled by hormones and genitals, accordingly. 

As a conclusion, the choices were indeed: (c) estradiol

Step 6: Given Information (part d)

steroid hormones-  testosterone 

Step 6: Explanation of Correct Answer (part d)

part d) The endogenous hormones estradiol and testosterone are controlled by hormones and genitals, accordingly. 

As a conclusion, the choices were indeed: (d) testosterone.
