when cells respond to an extracellular signal, they most often convert the information carried by this molecule from one form to another. What is this process called? - Answer-signal transduction When does signal transduction begin? - Answer-when the receptor on a target cell recieves and incoming extracellular signal and then produces intracellular signaling molecules that alter cell behavior extracellular signal molecules, released locally example: inflammation regulation at site of infe...

Describe the role that motor proteins play in the extension of the axon correct answers Motor proteins move along the microtubule and microfilament tracks transporting cargoes using energy from ATP hydrolysis. The motor protein kinesin moves components towards the growth cone or plus end of MTs while dynein move components to minus end of the MTs or back towards the cell body. What seems to be the most important factor for the selection of the neurite to become the axon? Describe some evidenc...
