Consider three groups of solutes: (i) steroid hormones, fatty acids,and other lipids; (ii) inorganic ions; and (iii) polar organic solutessuch as glucose and amino acids. What is the principal mechanismby which each group crosses cell membranes passively? Why domembers of the first group cross in a fundamentally different wayfrom solutes belonging to the other two groups?

Which of these answers explains why synaptic vesicles only releasee their neurotransmitter cargo in response to a signal? A) the necessary Rab proteins are not synthesized until an action potential arrives B) vesicle formation at the trans-Golgi network cannot occur in the absence of plasma membrane depolarization C) an additional protein, synaptotagmin, makes vesicle fusion dependent on the calcium concentration D)a plasma membrane transporter is needed to actively pump neurotransmitter into the synaptic cleft. These are inactive until membrane depolarization
