2.03 early cells alternate assignment
#3- look at table 2 below.
a) which molecule will probably require active transport to move into the cell?
b) how do you know?
table 2.
size
charge
concentration
molecule a
large
positive
higher outside
molecule b
small
negative
higher outside
molecule c
small
none
higher outside
molecule d
small
higher inside

Cells a and b are the same size and shape, but cell a is metabolically quiet and cell b is actively consuming oxygen. oxygen will diffuse more quickly into cell because . b the oxygen molecules inside cell b have a higher kinetic energy b. a its membrane transport proteins will not be saturated c. a the diffusion gradient there is shallowerd. b the diffusion gradient there is steeper
