Question 1

Which statement best describes how obesity increases free estrogen in the blood?

Accepted Answer

A) Estrogen is synthesized in adipose tissue,so higher fat mass raises the amount of estrogen in the blood.

C) Estrogen is synthesized in the liver as a result of lipotoxicity and is secreted into the blood. 
D) Both (a)and (b).
