Equilibrium

1. Equilibrium • condition in which the concentration of a substance is equal throughout a space.

2. ATP is associated with what Organelle? • Mitochondria • ATP (energy) is associated with which one, passive or active transport? • Active Transport • Draw a picture showing the process of passive diffusion and then write a brief description: • Diffusion usually results in _______________________ • Equilibrium

4. Typical red blood cells

5. Figure A represents a cell in a(n) hypertonic hypotonic isotonic solution. How do you know? Figure B represents a cell in a(n) hypertonic hypotonic isotonic solution. How do you know? Figure C represents a cell in a(n) hypertonic hypotonic isotonic solution. How do you know?

6. A phospholipidbilayer has two parts: • Polar heads – • hydrophillic (love ______________) • Nonpolar tails – • hydrophobic (fear ______________) • Active transport – against the concentration gradient or with the concentration gradient (high to low or low to high)??

7. Bulk Transport • Endocytosis • into the cell thru vesicles • Phagocytosis – “PAC MAN” • the eating up movement of solid material into cells • Pinocytosis – Pino (Vino)cytosis – • cell drinking moment of liquids into cells • Exocytosis – • EXit – movement of particles out of cell

8. Name the 3 types of passive transport and compare them using a T-chart: NO NRG Movement of particles across the concentration gradient from hi to lo Involves a protein channel or carrier in order to move larger particles or charged particles from hi to lo The movement of water across a selectively-permeable membrane from hi to lo in order to achieve equilibrium Diffusion Facilitated Diffusion Osmosis

9. Carrier Protein Potassium ions in Added for energy boost ATP against Sodium-Potassium Pump Moves ___________ the concentration gradient Phospholipid Sodium ions out
