This quiz for Academic Success Week 07 focuses on Lipid Metabolism & System-based practice. It covers key topics such as HMG-CoA reductase activity, cholesterol biosynthesis, and the role of thyroid hormones in hypercholesterolemia. Essential for students in medical and biochemical fields, it tests crucial understanding relevant to clinical practices.
Increased synthesis of fatty acids in adipose tissue due to excess free fatty acids released from adipose tissue
Decreased gluconeogenesis due to lack of activation of pyruvate carboxylase
Decreased levels of free fatty acids and undetectable ketone bodies in the plasma due to inactivation of LPL
Increased synthesis and recycling of fatty acids by the liver leading to increased adipose tissue storage of fats
Increased beta-oxidation due to increased activity of hormone sensitive lipase with subsequent increase in ketone bodies in plasma
Rate this question:
The patient can go into cardiac arrest because of lack of fatty acids for ATP production.
A plasma sample taken 45 minutes after a meal would reveal high levels of triglycerides due to lack of function of adipose tissue lipoprotein lipase
Coma could result because of lack of fatty acids as fuel for the brain
The patient would present with low levels of plasma ketone bodies due to lack of uptake of fatty acids in liver
A plasma sample would reveal both low levels of triglycerides and glucose
Activation of fatty acid synthetase
To act as a precursor for addition of one carbon units
Activation of acetyl-CoA carboxylase
To add the activated carbon dioxide in the formation of malonyl-CoA
Activation of carnitine acyl transferase
Rate this question:
Their synthesis in the liver is increased after a meal containing cholesterol and cholesterol esters
They both contain CoA
When the LDLR is up-regulated, HMG-CoA reductase is switched on.
HMG-CoA reductase is activated when the LDLR is down-regulated and the cell requires cholesterol
Both HMG-CoA reductase and the LDLR are synthesized in response to high levels of intracellular cholesterol
Rate this question:
Increasing the conversion of cholesterol to bile acids
Inhibiting the formation of HMG-CoA
Preventing the reabsorption of bile acids from the intestine
Inhibiting the formation of mevalonate
Inhibiting the absorption of cholesterol from the diet

Elevated insulin levels, which cause the hypoglycemia and increase fatty acid mobilization from adipose tissue
Rate this question:
They are involved in the activation of choline, ethanolamine and diacylglycerol (DAG)
They provide the energy to convert choline to ethanolamine
They are involved in the phosphorylation of choline and ethanolamine
They are recognition molecules for phospholipid transferases
They are important in signal transduction

Rate this question:
Ignore the special cause as it is likely not important .
Although the trend was upward, it isn’t important since the most recent data (patients 28- 30) show that the process is improving.
Start a patient access committee for mental health
Patient access to appointment is not a physician's responsibility This work should be referred to administrative staff.
Investigate the special cause signal to find why the time from referral to appointment increased.

Rate this question:
HMG-CoA red uctase is activated due to low levels of thyroid hormones
Low density lipoprotein receptors are upregulated in these patients
Large amounts of cholic acid are reabsorbed from the intestine which feeds back to 7-a-hydroxylase resulting in inactivation of the enzyme
High levels of thyroid hormones increase the synthesis of cholesterol
Thyroid hormones are necessary for the activation of 7a-hydroxylase
