__solvent_________________.
9. The part of a solution that consists of the dissolved particles is
the _solute_____________.
10.
If the concentration of solutes outside of the cell is lower than
the solutes inside of the cell, it is said to be
__hypotonic____________________.
11.
The type of passive transport where molecules pass through proteins
is known as __facilitated_______________________.
12.
If there is a higher amount of solvent outside of the cell than
inside of the cell, the direction that water will move will cause the
cell to ___swell____________________.
13.

Enzymes
1. What is the difference between an enzyme and a catalyst? And how do
they slow down the speed of a reaction?
An enzyme is a biological catalysts; the speed up the rate of
reaction by lowering activation energy
2. What is the importance of the active site on an enzyme?
This is where the substrate binds to the enzyme
3. What is a substrate? This is the reactant needed for the reaction
to take place; connects to the enzyme.
