Ligand is another name for which molecule in a cellular communication pathway?
A signaling molecule
B cellular membrane
C receptor protein
D carrier protein
Which step below would be the final step in a signal transduction pathway?
A Phosphorylation of proteins.
B Change in gene expression.
C Binding a ligand to a receptor.
D Activation of a protein.
Which part of the neuron receives a signal from other neurons or sensory cells?
B cell body (soma)
Rearrange the steps of the action potential by using the graph above.
Depolarization (All or none rule)
Describe each step of the action potential using the graph and the numbered steps. Make sure you are talking about Na+ and K+ changing gradients as well as change in voltage of the cell. You should also mention the types of channels opening and closing.
