From which of the following can gluconeogenesis generate glucose? A) Amino acids B) Glycogen C) Lactate D) ATP
Understand the Problem
The question is asking which substances can be used in the process of gluconeogenesis to produce glucose. It provides four different options to evaluate.
Answer
Amino acids and lactate
Gluconeogenesis can generate glucose from amino acids and lactate.
Answer for screen readers
Gluconeogenesis can generate glucose from amino acids and lactate.
More Information
Gluconeogenesis is a metabolic process that generates glucose from non-carbohydrate sources like lactate and glucogenic amino acids. Glycogen is not a precursor for gluconeogenesis as it is directly converted to glucose through glycogenolysis.
Tips
A common mistake is thinking glycogen is used in gluconeogenesis when it is actually used in glycogenolysis. Also, ATP is often misunderstood as a substrate but it is actually a source of energy for the process.
