Which of the following lipoproteins distributes dietary lipids? chylomicron The interaction of chylomicrons with lipoprotein lipase is stimulated by which of the following Apo proteins? ApoC II Nascent chylomicrons are synthesized in which tissue? Intestine Bile salts are synthesized from cholesterol and are used for the emulsification of dietary lipids. What is the primary fate of bile salts during digestion? They are reabsorbed in the ileum Nascent chylomicrons ...

In what part of the compartment of the cell does fatty acid synthesis take place? Mitochondria ER Cytosol Lysosomes Which of these hormones does not play a role in the mobilization of fatty acids from triacyglycerol stores in the fasted state? Desnutrin Lipoprotein lipase Monoacylglycerol lipase Hormone-sensitive lipase 1 / 1 pts Question 3 The liver is the primary site of fatty acid synthesis and also stores large amounts of triacylglycerols. True False 1 / 1 pts Question 4 Wher...

Malate can be converted to pyruvate in the cytosol. Which of the following compounds is directly generated in this conversion and is essential for fatty acid synthesis? FADH2 ATP Acetyl-CoA NADPH correct answer: NADPH An increase in the ratio of insulin to glucagon will increase the activity of which of the following enzymes (+ indicates activity is increased; - indicates activity is not increased by insulin)? Hormone sensitive lipase Acetyl-CoA carboxylase Phosphofructokina...

An 11-year-old girl is brought to the emergency department by her father. He reports she has recently been very thirsty and needing to make frequent trips to the bathroom. At her soccer game today, she complained of lightheadedness and that the symptoms did not resolve even after drinking a power beverage. A rapid dipstick test revealed glucose in her urine and further diagnostics are consistent with a diagnosis of type 1 diabetes. Evaluation of this girl's liver would reveal an increased rate ...

Under fasting conditions (ratio of insulin to glucagon <1), elevated glucagon will activate which of the following enzymes? correct answer: Hormone sensitive lipase The process of ketogenesis refers to the conversion of acetyl CoA to which of the following compounds? correct answer: D-3-hydroxybutyrate or B-hydroxybutyrate During the fasted state, lipolysis is facilitated by the action of hormone sensitive lipase. This enzyme requires which of the following post - translational modifi...

What substrate depletes when you "hit the wall" - correct answer glycogen What substrate depletes when you lose autonomic NS function? - correct answer glucose function of NADH and FADH? - correct answer hydrogen transporter 3 types of ATPase in muscle? - correct answer myosin sarcoplasmic reticulum Na/K rate limiting enzyme for glycolysis and glycogenolysis - correct answer phosphofructokinase enzyme that changes pyruvate to lactate - correct answer lactate dehydrogenas...
