COMPLETE QUESTIONS AND VERIFIED
ANSWERS
●● The energy required during active transport is needed to? Answer:
counteract diffusion
●● an increase in solute concentration will ___ energy Answer: increase
●● Which of the following is false?
-There is more Na+ outside the cell than inside
-There is more K+ outside the cell than inside Answer: False- There is
more K+ outside the cell
●● In a normal cell at rest the electrical driving force want to move
K+____ the cell Answer: into the cell
●● In a normal cell at rest , the chemical driving force wants to move
K+ ____ the cell Answer: out of the cell
●● If you were told that a given cell has a resting membrane potential of
40+mV what conclusion could you draw about the cell? Answer: the cell
is more permeable to Na+ at rest than it is to K+
, ●● In a normal cell at rest, which driving force has a strong effect on K+
Answer: chemical
●● For a normal cell, if the membrane potential were 0mV you would
expect Na+ to Answer: move into the cell
●● For a normal cell, if the membrane potential were --100mV, you
would expect K+ to: Answer: move into the cell
●● If a cell has a membrane potential of -65mV what does this mean?
Answer: the inside of the cell is 65m more negative than the outside
●● which of the following is an example of con transport? Answer:
movement of glucose and Na+ into the cell
●● Why is energy needed for the Na+/K+ ATPase? Answer: because
Na+ and K+ are being moved against its concentration gradient
●● Solution A has a concentration of 8M glucose. Solution B has a
concentration of 3M glucose. Which solution has more free water
molecules? Answer: Solution B
●● True or false: Osmosis is always a passive process. Answer: True
