Question

10) Long-chain fatty acyl-CoAs are transported across the mitochondrial inner membrane using the carrier ________.

13) While a number of hormones can stimulate lipolysis, the primary hormonal effects in adipose tissue are mediated by ________ in response to stress and by ________ during fasting.

14) Ketone bodies can be used as an alternative fuel source by the liver. (True/False)?

15) ________ are formed (primarily in the liver) when acetyl CoA accumulates beyond its capacity to be oxidized or used for fatty acid synthesis.

Explanation / Answer

10) Long-chain fatty acyl CoAs are transported across the mitochondrial inner membrane using the carrier carnitine carrier system.

13) While a number of hormones can stimulate lipolysis, the primary hormonal effects in adipose tissue are mediated by cyclic AMP in response to stress and by cyclic AMP during fasting.

14) Ketone bodies can be used as an alternative fuel source by the liver.

The above statement is False because ketone bodies are not utilized by the liver due to the absence of an enzyme Thiophorase which cleaves acetoacetyl Co A to acetyl CoA.

15) Acetone are formed (primarily in the liver) when acetyl CoA accumulates beyond its capacity to be oxidized or used for fatty acid synthesis.
