Neuron Structure answers
Neuron Structure (POGIL answers)1. Remember that typically signaling in neurons moves from the dendrite end along the axon to the synaptic terminal end.2. Dendrites3. 4. A phospholipid bilayer of neuron located near the dendrite end. Situated with the lipid bilayer are protein channels that are specific to sodium and potassium ions. The membrane also has situated withinit sodium potassium pumps. ATP is required to move sodium out of the cell and potassium into the cell because these directions are against the concentration gradient for these ions (low to high). The resting potential (difference in membrane potential from one side to the other is -70 mV. 5. phospholipid, sodium ion, potassium ion, channel protein6a. Outside6b. Because they are polar.6c. Into the cell. 7a. The interior. 7b. Toward the exterior of the neuron (extracellular side). 8. The presence and hydrolysis of ATP.9. Na+ out.10. K+ in. 11. 3 Na+ out for 2K+
