Questions and Answers

What is the final step in TAG synthesis?

  • Secretion of adipose hormones
  • Activation of lipogenic enzymes
  • Diacylglycerol acyltransferase (DGAT) reaction (correct)
  • Lipolysis of triglycerides

    • Under what physiological conditions do adipocytes mobilize their TAG stores through lipolysis?

  • After a meal, due to increased insulin
  • When metabolic fuels are low and/or energy demand is high (correct)
  • When adipocytes secrete hormones like leptin and adiponectin
  • When adipose tissue becomes insulin resistant

    • What are the enzymes involved in the lipolysis of triglycerides?

  • Lipogenic enzymes
  • Adipocyte triglyceride lipase (ATGL) and hormone sensitive lipase (HSL) (correct)
  • Monoacylglycerol lipase (MGL) and diacylglycerol acyltransferase (DGAT)
  • All of the above
