Diffusion

The movement of molecules from an area of high concentration to an area of low concentration

Concentration Gradient

The difference in the concentration of the molecules across a distance

Cytolosis

Occurs when the cell bursts due to an osmotic imbalance that has caused excess water to enter the cell

Active Transport

Molecules move against the concentration gradient (low to high) and the cell uses energy

Passive Transport

Substances that cross the cell membrane w/o any input of energy by the cell (high to low)

Enters with water

Plasmolosis

The process in which cells lose water in a hypertonic solution

Surface Area's Effect on Diffusion

Larger surface area = Faster diffusion rate

Hyper/hypo/iso-tonic solutions

Facilitated Diffusion

Passive transport - Enter cell through their own ion channel

Sodium-Potassium Pumps

Carrier protein that transports Na+ and K- UP their concentration gradients

Endocytosis

Calls ingest external fluid, macromolecules and large particles

Exocytosis

Process by which substances are released from a cell through a vesicle that fuses with the membrane and forces the substance out

Ion Channels and Carrier Proteins

Move charged particles across the cell membrane by using chemical energy from ATP

Homeostasis

The movement of a stable level of internal conditions

Ex: Temperature

Equilibrium

Concentration of the molecules will be the same throughout
