Q: What are the 2 parts of a glycoprotein?
Answer:
1) Many, short carbohydrate chains 2) Attached to a protei
Q: Identify 2 roles of glyco- lipids and proteins in cell membranes?
Answer:
1) Stabilize membrane structure 2) Receptor molecules - Bind w/ particular
substances
Q: Diffusion
Answer:
Net movement of molecules (or ions) from high to low concentration

Q: What 4 factors affect the rate of diffusion?
Answer:
1) 'Steepness' of the concentration gradient- The difference in the concentration of
the substances on the 2 sides of the surface 2) Temperature- High temperature=ions
and molecules have more kinetic energy than if the temperature was low 3) Surface
area across which diffusion is taking place- greater surface area=more molecules or
ions can cross it at any one moment, faster diffusion 4) Nature of the molecules or
ions- Large molecules need more energy than small ones. Nonpolar diffuse more
easily through cell membranes than polar ones.
Q: Facilitated Diffusion
Answer:
Diffusion of a substance through protein channels in a cell membrane
Q: Passive Process
Answer:
Doesn't require energy

Q: Osmosis
Answer:
Type of diffusion involving water molecules only
Q: Water Potential
Answer:
tendency of water molecules to move from one place to another
Q: Define osmosis in terms of water potential.
Answer:
The movement of water molecules from a
region of higher water potential to a region of lower water potential through a
partially
permeable membrane.

Q: Solute Potential
Answer:
The amount that the solute molecules lower the water potential of a
solution
Q: What effect does pressure have on water potential?
Answer:
Greater Pressure = Greater tendency for H2O molecules to be forced back
Q: Pressure Potential
Answer:
The contribution made by pressure to H2O potential
Q: Turgid
Answer:
Plant cell fully inflated with water
