Textbook Question
Chapter 8, Problem 8.3PS
Mechanisms of Transport. For each of the following statements, answer with a D if the statement is true of simple diffusion, with an F if it is true of facilitated diffusion, and with an A if it is true of active transport. Any, all, or none (N) of the choices may be appropriate for a given statement.
- (a) Requires the presence of an integral membrane protein
- (b) Depends primarily on solubility properties of the solute
- (c) Doubling the concentration gradient of the molecule to be transported will double the rate of transport over a broad range of concentrations.
- (d) Involves proteins called ATPases
- (e) Work is done during the transport process.
- (f) Applies only to small, nonpolar solutes
- (g) Applies only to ions
- (h) Transport can occur in either direction across the membrane, depending on the prevailing concentration gradient.
- (i) ΔG° = 0
- (j) A Michaelis constant (Km) can be calculated.

Multiple Choice. Imagine a solution containing only water, sodium, and glucose. If a voltage is applied to the solution, glucose would move:
(a) There would be no net movement of glucose
(b) In the opposite direction of sodium
(c) In the same direction and speed as sodium
(d) In the same direction as sodium, but slower.
(e) In the same direction as sodium, but faster.
Frog poison. Batrachotoxin (BTX) is a steroidal alkaloid from the skin
of Phyllobates terribilis, a poisonous Colombian frog (the source of
the poison used on blowgun darts). In the presence of BTX, Na+Na*
channels in an excised patch stay persistently open when the
membrane is depolarized. They close when the membrane is
repolarized. Which transition is blocked by BTX?
