Question: 161

11. The majority of triacylglycerol stored in adipocytes originates from:

  • A. synthesis in the adipocyte.
  • B. dietary intake.
  • C. ketone bodies.
  • D. synthesis in the liver.

Correct Answer: D

Explanation:

The liver is the major metabolic organ in the body and is responsible for much of the synthesis and interconversion of fuel sources. Most of the triacylglycerols that are synthesized in the liver are transported as VLDL to adipose tissue for storage. Both the adipocytes, choice (A) and dietary intake, choice (B), constitute a minor source of triacylglycerol.
