Cell Transport and Water potential

Osmosis

diffusion of water

Active Transport

movement requiring ATP

Passive Transport

movement that doesn't require ATP

Diffusion

movement from from high to low

Facilitated Diffusion

the transport of larger molecules thru a channel protein

Endocytosis

taking things into the cell

Phago

food

Pino

liquid

Exocytosis

process of the cell releasing material

Homeostasis

state of balance in the body

Stimulus

something in the environment that causes a change

Response

action of the organism as a result of stimulus

Feedback Loops

processes by which the body maintains levels

Positive Feedback Loop

Process by which stimulus causes a response which will increase stimulation

Negative Feedback Loop

Receptors detect change and initiate response that will counter that change

What hormone move glucose into the cell

Insulin

What hormone helps turn glycogen into glucose

glucagon

Hypertonic

water leaving the cell

Hypotonic

water entering the cell

Isotonic

no movement of water

i

ionization constant

C

molar concentration

R

pressure constant

Pressure constant

.0381

T
