E XA M Q U EST I O N S


Q1 QUESTION 1 OF 188
what is the definition of homeostasis?
CORRECT ANSWER

the maintenance of a relatively stable and constant internal environment



Q2 QUESTION 2 OF 188
why is there a limit to how large a cell can be?
CORRECT ANSWER

as the size of the cell increase, the distance between the core of the cell and the surface of the cell
increases, making it more difficult to transport materials between those two areas



Q3 QUESTION 3 OF 188
which type of lipid is most abundant in plasma membranes?
CORRECT ANSWER

phospholipids



Q4 QUESTION 4 OF 188
if a membrane-bound protein is an integral protein, how might we best describe this protein?



Page 2

, CORRECT ANSWER

this is a protein that spans the entire width of the plasma membrane, such that is has surfaces that
project into both the extracellular fluid and the intracellular fluid.



Q5 QUESTION 5 OF 188
there are several types of membrane-bound proteins that can be found in plasma membranes.
membrane-bound proteins that function to catalyze specific chemical reactions are called
CORRECT ANSWER

enzymes



Q6 QUESTION 6 OF 188
there are several types of membrane-bound proteins that can be found in plasma membranes.
membrane-bound proteins to which chemical signals/messengers bind are known as
CORRECT ANSWER

receptors



Q7 QUESTION 7 OF 188
there are several types of membrane-bound proteins that can be found in plasma membranes.
membrane-bound proteins that enable the body to distinguish its own cells from foreign cells
are known as
CORRECT ANSWER

cell-identity markers



Q8 QUESTION 8 OF 188
let's assume that the concentration of glucose inside a cell is 0.50osm and that we have
immersed that cell in a solution of glucose that has a concentration of 0.25osm. glucose
requires a carrier protein to move across the plasma membrane. if we want to move glucose
from the outside of the cell to the inside of the cell, would the carrier protein be carrying out
facilitated diffusion or active transport?
Page 3

, CORRECT ANSWER

active transport



Q9 QUESTION 9 OF 188
if the osmolarity inside a cell is 0.3osm, and we place that cell in a beaker of sodium chloride
that has a concentration of 0.3osm, how do we best describe that solution of sodium chloride?
CORRECT ANSWER

isotonic



Q10 QUESTION 10 OF 188
if the osmolarity inside a cell is 0.3osm, and we place that cell in a beaker of sodium chloride
that has a concentration of 0.1osm, how do we best describe that solution of sodium chloride?
CORRECT ANSWER

hypotonic



Q11 QUESTION 11 OF 188
if a red blood cell is placed into a hypertonic solution, what will happen to the cell with
regards to osmosis?
CORRECT ANSWER

osmosis will occur such that water moves from the inside to the outside of the cell, causing the
cell to shrink in volume



Q12 QUESTION 12 OF 188
the release of materials from cells via vesicles that fuse with the plasma membrane is called:
CORRECT ANSWER

exocytosis
