In the liver, which of the following key inhibitory events ensures that newly synthesized palmitoyl-CoA is not immediately oxidized? Carnitine palmitoyl transferase-I (CPTI) by palmitoylcarnitine Carnitine palmitoyl transferase-II (CPTII) by acetyl-CoA Acyl-CoA synthetase by malonyl CoA Carnitine palmitoyl transferase-I (CPTI) by malonyl-CoA Carnitine acylcarnitine translocase (CAT) by palmitoyl-CoA - ANSWERSCarnitine palmitoyl transferase-I (CPTI) by malonyl-CoA Malonyl-CoA pr...

An individual goes to bed around 8 pm and doesn't wake up until 9 am the next morning. During this time, which of the following is the primary oxidizable substrate in the skeletal muscle? - ANSWERSFree fatty acids Under fasted conditions as described above, the skeletal muscle and liver would be oxidizing free fatty acids as a means of producing ATP. A well, 2-year-old girl presents to the clinic with symptoms of a viral illness. Her parents report she has had bouts of vomiting and diarrh...

What are the main products of beta oxidation? - ANSWERS1 NADH, 1 FADH, 1 Acetyl CoA So in the case of an 11-year-old girl brought to the emergency department by her father, he's reporting that she's been very thirsty and needing to make frequent strips to the bathroom. Today, she reported lightheadedness during a soccer game and symptoms did not resolve after drinking a power beverage. A rapid dipstick test revealed glucose in her urine and further diagnosis are consistent with a diagnosis ...

The cellular uptake of LDL increase intracellular cholesterol levels. This has which of the following impacts on de novo cholesterol synthesis? - ANSWERSIncreases degradation of HMG-CoA reductase Dietary cholesterol is primarily transported in the body by which of the following lipoproteins? - ANSWERSChylomicrons. Cholesterol and TG from diet are transported from intestine to liver via chylomicrons. The LDL receptor is also highly regulated in the cell. Which of the following proteins t...

In the fasted state, fatty acyl-CoA are transported across the mitochondrial membrane. The transport of fatty acids via carnitine palmitoyl transferase I (CPTI) can be directly inhibited by which of the following compounds? - ANSWERSMalonyl CoA Under fasting conditions (ratio of insulin to glucagon <1), elevated glucagon will activate which of the following enzymes? - ANSWERSHormone sensitive lipase Glucagon will increase levels of lipolysis through the phosphorylation and activation of...
