In Your Research, You Label Two Proteins (P1 and P2)

Multiple Choice

In your research, you label two proteins (P1 and P2) , with fluorescent dyes and watch as they move the length of a cultured neuron toward the axon terminal. P1 moves very quickly relative to P2. You might conclude that

A) P1 is not a protein
B) P1 is involved in retrograde axoplasmic transport
C) P1 is likely a protein that is associated with transport vesicles
D) P1 is a protein that is unlikely to be associated with transport vesicles
E) All of the above are true
