Patients with mutations leading to defective beta-oxidation of fatty acid usually have hypoglycemia because of 
Select and explain. 
A. Less ATP for gluconeogenesis, B. Less acetyl CoA for glucose formation, C. Increased fatty acids decrease glucose utilization, D. Fatty acids inhibit transpo of glucose for metabolism
B: Less acetyl CoA for glucose formation
Answer: B: Less acetyl CoA for glucose formation 
Explanation: Acetyl-coenzyme A or acetyl-CoA is an impoant molecule that paicipates in many biochemical reactions in protein, carbohydrate, and lipid metabolism. Its main function is to deliver the acetyl group to the citric acid cycle (Krebs cycle) to be oxidized for energy production. Ref-Sathyanarayana 4/e p399
