isotonic
question 3
select one answer.
a cell will uptake large molecules from the extracellular fluid by the process of
diffusion
pinocytosis
exocytosis
endocytosis
active transport
question 4
select one answer.

sodium ions are more highly concentrated outside the cell, in the extracellular fluid. which process would be used to return any sodium ions that leaked into the cell back to the extracellular fluid?
active transport
osmosis
simple diffusion
exocytosis
facilitated diffusion
question 5
select one answer.

an animal cell placed in a hypotonic solution will
burst
shrivel
stay the same
question 6
select one answer.

a substance, such as glucose, will enter a cell following its concentration gradient, from the blood and tissues, through the membrane, and into the cytoplasm. such movement of glucose has a maximal capacity, does not require energy, and is specific only for glucose. how is the entry of glucose into the cell occurring?
by facilitated diffusion
by simple diffusion
by active transport
by osmosis
by endocytosis
question 7
select one answer.

increasing the concentration gradient:
does not alter the rate of diffusion
decreases the rate of diffusion
increases the rate of diffusion
question 8
select one answer.

active transport could also be called facilitated diffusion.
true
false
question 9
select one answer.

an immune cell would engulf a pathogenic cell using the process of: ?
endocytosis
passive transport
exocytosis
active transport
question 10
select one answer.
protein transporters that move materials against a concentration gradient are active transport proteins.
true
false
