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: Biochemistry
Which of the following can participate in gluconeogenesis? 
Select and explain. 
A. Acetyl coA, B. Propionyl coA, C. Muscle glycogen, D. All of the above
B: Propionyl coA
Answer: B: Propionyl coA 
Explanation: Propionyl coA
        ↓
Succinyl coA
        ↓
Fumarate
        ↓ 
   Malate
        ↓
Oxaloacetate →Gluconeogenesis
Note : Acetyl coA which is released from even chain fatty acids can't participate in gluconeogenesis. Muscles lack glucose-6-phosphatase and hence can't.
