This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Unknown
Which of the following glycolytic enzyme is used in gluconeogenesis ? 
Select and explain. 
A. Glucokinase, B. Pyruvate kinase, C. Aldolase, D. Phosphofructokinase
C: Aldolase
Answer: C: Aldolase 
Explanation: Aldolase is the enzyme which catalyses reversible reaction of glycolysis. So this enzyme is utilized in gluconeogenesis.
Glucokinase, pyruvate kinase and phosphofructokinase are enzymes which catalyse irreversible reaction of glycolysis and which are bypassed by different sets of enzymes during gluconeogenesis.
