Included Quiz Questions

Which statement regarding non-hormone signaling methods is true?

They can be much more rapid than hormone signaling methods.
They include nerve transmission and protein degradation.
They require cells to expand.
They are not as rapid as hormone signaling methods.

Which statement regarding nerve signaling is true?

It involves changes in ion gradients.
It starts with potassium gates opening.
It has a cell with low sodium outside to start.
It is initiated by ion channel blocking molecules.

What causes the action potential in the neurons?

The movement of ions across the cell membrane.
The movement of proteins across the cell membrane.
The movement of cAMP molecules across the cell membrane.
The movement of GTP molecules across the cell membrane.
The movement of prostaglandins across the cell membrane.

What is the role of the Na+/K+ pump in the neuron cell membrane?

To move Na+ ions out of the cell and pump K+ ions back into the cell to recover the resting membrane potential.
To move K+ ions out of the cell and pump Na+ ions back into the cell to recover the resting membrane potential.
To move K+ ions out of the cell and pump Na+ ions back into the cell to set the action potential.
To move Na+ ions out of the cell and pump K+ ions back into the cell to set the action potential.
To move Na+ and K+ ions out of the cell to recover the resting membrane potential.
