A & P I-Lab 5
The Cell:Transport Mech. and Cell permeability
| Question | Answer |
|---|---|
| Rate of diffusion is determined by? | 1. Size of molecule 2. Tempature 3. The medium (what they travel thru) |
| High to Low is the way to go | High to low is the way to go :-) |
| Molecular motion..... | Reflects the kinetic energy of molecules. It's random and erratic like ME....lol |
| Velocity of molecular movement... | is lower in larger molecules and increase with increase temp. |
| Hypertonic | if it contains more non-penetrating solutes particles then the interior of the cell. |
| Hypotonic | if it contains fewer nonpenetrating solute particles. |
| Difusion | is the movement of molecules from a region of their higher concentration to a region of their lower concentration. ****It's driving force is KINETIC EVERY of the molecules themselves***** |
