Gluconeogenesis

What is the end product of gluconeogenesis?

• pyruvate

• acetyl-CoA

• glucose

• lactate

What is the primary function of gluconeogenesis?

• to create glucose from non-carbohydrate sources

• to store excess glucose as glycogen

• to breakdown glycogen to glucose

• to regulate blood sugar levels

Which organ is primarily responsible for gluconeogenesis?

• liver

• pancreas

• kidney

• muscle

What is the primary source of energy for gluconeogenesis?

• carbohydrates

• lipids

• amino acids

• lactate

What is the role of the enzyme pyruvate carboxylase in gluconeogenesis?

• It converts pyruvate to glucose

• It converts glucose-6-phosphate to glucose

• It converts oxaloacetate to phosphoenolpyruvate

• It converts lactate to glucose

What is the final step of gluconeogenesis?

• Conversion of pyruvate to glucose

• Conversion of glucose-6-phosphate to glucose

• Conversion of fructose-1,6-bisphosphate to glucose

• Conversion of lactate to glucose

What are some examples of non-carbohydrate sources that can be used for gluconeogenesis?

• Lactate, glycerol, and amino acids

• Fructose, glucose and sucrose

• Starch, cellulose, and chitin

• Cholesterol, fatty acids, and triglycerides

In what conditions does the body rely more heavily on gluconeogenesis?

• When blood sugar levels are high

• When blood sugar levels are low

• When glycogen stores are high

• When insulin levels are high
