Where are triglycerides produced in the body and what hormone regulates their production?

I. In the adipose tissue and liver. Their production is regulated by insulin and glucagon.

II. In the blood and liver. Their production is regulated by epinephrine and antidiuretic hormone.

III. In the blood as very-low density lipoproteins and chylomicrons. Their production is regulated by epinephrine and growth hormone.

IV. In the muscle. Their production is regulated by growth hormone.
