Cellular Transport and Biomolecules

2. LIPID BILAYER #13 The cell membrane is made up of two
layers of lipids, specifically phospholipids

3. Protein channel specific substances across a cell membrane.
 a protein that allows the transport of
specific substances across a cell membrane. 

4. Cell membrane
14. The cell membrane is a semi-permeable Membrane that allows some things to pass while others cannot
15. In osmosis, WATER moves from an area of HIGH to an area of LOW concentration.
16. In diffusion, MOLECULES move from an area of HIGH to an area of LOW concentration.

5. Transport of molecules in and out of the cell
The dark molecules are too large to pass through
the membrane
b. The Starch concentration is greatest on the right side
of the beaker
c. The water concentration is greatest on the left
d. The dark molecules would move the left if they
could because diffusion occurs from high to low concentration

6. Hypotonic solution
18a. Salt inside the cell = 65% and outside the cell 40%.

7. Hypertonic solution
18 b. Sugar inside the cell 27% and outside 80%.

11. ENZYMES What is he function of an enzyme?
What is he function of an enzyme?
2. Acts as a biological catalyst, speeds up the rate of a chemical reaction
How do temperature and pH affect enzymes?
3. Most enzymes work best in certain conditions.  A change in those condit ions will cause denaturing.   Too high or too low temps or pH will cause the enzyme to no longer work properly. This is called denaturing (#8)
4. Acids have pH BELOW 7 
5. Bases have pH ABOVE 7
6. Neutral solutions have pH of 7
