What our notes say
- The last irreversible reaction of gluconeogenesis is catalyzed by; (Biochemistry I End of Year MCQs — September 2020 (Past Paper))
- They participate in gluconeogenesis by catalysing the transfer of amino groups (Paediatrics end of second semester exam (MBPE 4300): 4 October 2022, cardiology,)
- The pathway of gluconeogenesis shares seven steps with the pathway of glycolysis (bchem EOY 2011 — Past Paper Questions & Answers)
- B—false, alcohol metabolism raises the NADH/NAD⁺ ratio, which inhibits gluconeogenesis (a cause of alcohol-induced hypoglycaemia). (bchem EOY 2011 — Past Paper Questions & Answers)
- There exists an enzymatic difference between aerobic glycolysis and gluconeogenesis where they share steps but do not share _ steps. (Biochemistry Mid-Semester Exam — 2016 (Past Paper))
- Carbs: Glycolysis (glucose→2 pyruvate, 2 ATP) → Krebs cycle (Acetyl-CoA, 2 ATP) → ETC (~34 ATP) → Gluconeogenesis/Glycogenesis/Glycogenolysis (Complete Nutrition Science: Macronutrients & Health Foundations)

Practice questions on Gluconeogenesis
The last irreversible reaction of gluconeogenesis is catalyzed by;
- Phosphoglycerate mutase
- Pyruvate kinase
- Hexokinase
- Glyceraldehyde-3-phosphate dehydrogenase
- Glucose-6-phosphatase ✅ Answer: E. Glucose-6-phosphatase
Answer: A. Glucose-6-phosphatase catalyses the final, irreversible step of gluconeogenesis, releasing free glucose from glucose-6-phosphate. ---

- Fatty acid
- Glycerol
- Pyruvate
- AcetylCoA
- propionylCoA
Answer: A.
