Which Statement is TRUE Regarding Fatty Acids in Adipocytes

Question

Which statement is TRUE regarding fatty acids in adipocytes?
A) They are primarily bound to albumin and stored in lipid droplets.
B) They cannot be oxidized for energy in this tissue.
C) In adipocytes, fatty acids from the bloodstream are assembled into triglycerides by esterifying them to glycerol.
D) There is constant movement of fatty acids in and out of adipose tissues that is independent of hormone signals.
E) All of the statements are true.

Accepted Answer

In adipocytes, fatty acids are assembled into triglycerides by esterifying them to glycerol. This is how adipose tissue stores excess energy in the form of triglycerides. The other statements are not entirely true: A) While fatty acids are stored in lipid droplets in adipocytes, they are not primarily bound to albumin. B) Fatty acids can be oxidized for energy in adipose tissue, but this is not their primary function. D) Movement of fatty acids in and out of adipose tissue is regulated by hormone signals.
