This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: General physiology, Subject name: Physiology
Ohograde axonal transpo involves all except 
Select and explain. 
A. Kinesin and Dynein molecular motors, B. Ohograde transpo moves from the cell body toward the axon terminals, C. Nerve Growth Factor, toxins, viruses transpo using kinesin, D. Mitochondria, vesicles containing neurotransmitters using kinesin
C: Nerve Growth Factor, toxins, viruses transpo using kinesin
Answer: C: Nerve Growth Factor, toxins, viruses transpo using kinesin 
Explanation: "Ohograde transpo occurs along microtubules that run along the length of the axon and requires two molecular motors, dynein and kinesin. The ohograde transpo moves from the cell body toward the axon terminals."
