Total questions: 10
Worksheet time: 2mins
What is the primary enzyme responsible for the conversion of ethanol to acetaldehyde in the liver?
Alcohol dehydrogenase
Catalase
MEOS
CBL: Case-Based Learning Scenario
Case: A 36 year old male is brought to the emergency department with confusion, nausea, and blurred vision. His friends report he had consumed homemade liquor the night before. His breath has a fruity odor, and fundus examination shows signs of optic nerve damage. Lab tests show high anion gap metabolic acidosis.
1. What is the most likely diagnosis?
Alcohol intoxication
Methanol poisoning
Fatty liver
Alcohol ketoacidosis
CBL: Case-Based Learning Scenario
Case: A 45 year old female presents to the clinic with severe abdominal pain, vomiting, and confusion. She has a history of binge drinking and reports consuming a large quantity of alcohol the previous night. Physical examination reveals jaundice and asterixis. Lab tests indicate elevated liver enzymes and a high anion gap.
1. What is the most likely diagnosis?
Acute liver failure
Pancreatitis
Alcohol withdrawal syndrome
Alcoholic hepatitis
Which of the following is a lipotropic factor important for preventing fatty liver?
Ethanol
Acetyldehye
NADH
Choline
alcohol-induced hypoglycemia, which gluconeogenic intermediate is reduced due to high NADH/NAD+ ratio?
Citrate
Pyruvate
Glucose
Acetyl-CoA
Which of the following metabolic changes does NOT occur in chronic alcohol use?
Fatty liver
Ketogenesis
Lactic acidosis
Increased gluconeogenesis
What is the calorific value (kcal/gm) of ethanol?
8
6
7
9
What is the primary metabolic pathway for ethanol oxidation in the liver?
Glycolysis
Citric acid cycle
Alcohol dehydrogenase pathway
Fatty acid synthesis
In the context of alcohol metabolism, what effect does a high NADH/NAD+ ratio have on the liver?
Increased fatty acid oxidation
Inhibition of gluconeogenesis
Enhanced ketogenesis
Decreased lactate production
In the context of alcohol metabolism, what is the consequence of increased NADH levels?
Promotion of lactic acid production
Inhibition of fatty acid synthesis
Enhanced protein synthesis
Increased gluconeogenesis
