Answer to Question 1

D
Feedback:
Active transport is what happens when cells use energy to move ions against an electrical or chemical gradient. Passive transport is another term for diffusion. There is no such thing as neutral transport. Cotransport is when the sodium ion and the solute are transported in the same direction.

Answer to Question 2

C
Feedback:
Ketamine has been associated with a bizarre state of unconsciousness in which the patient appears to be awake but is unconscious and cannot feel pain. This drug, which causes sympathetic stimulation with increase in blood pressure and heart rate, may be helpful in situations when cardiac depression is dangerous. Thiopental is a barbiturate anesthetic. Midazolam and propofol are nonbarbiturate anesthetics. None of these medications have this type of effect.
