What are 3 driving forces across the membrane?

What are 5 types of transport?

What factors affect Simple Diffusion?

What factors affect Facilitated Diffusion?

Function: Uses ATP directly for molecule transport (to push from low to high concentration)

Function: Uses electrochemical gradient for molecule transport

When 2 molecules are moving in the same direction in Secondary active transport, this is called

When 2 molecules are moving in different direction in active transport this is called

Definition: Diffusion of water through a membrane, always passive, unaffected by electric charge on cells

Definition: same concentration (no net water movement, cell will remain the same)

Definition: higher concentration (water gets out of cells, causing it to shrink)

Definition: Lower concentration (water gets in, causing the cell to swell or burst)

Function: Molecules enter the cells by vesicle formation

Function: Molecules are packaged into secretory vesicles inside the cell and released into the extracellular fluid

Endocytosis + Exocytosis =

3 factors affecting the strength of response

What happens in Upregulation?

What happens in down-regulation?

What are 3 types of Chemical messanger?

Function: Receptors are found in the cytosol or nucleus 
Binding of receptor will result in gene activation or deactivation

Signal transduction consist of

Three type of membrane bound receptors

Function: ligand binding causes the ion channel to open or close

Function: Ligand binding activaties the enzyme which will trigger cell response

Function: 
Opening or closing of ion channels 
Activating second messenger system

Channel linked receptors are

Enzyme linked receptors have...

G- protein coupled ion channles are...

Second messenger is also known as

Steps in cAMP second messenger system

How does termination of Second messenger system occur

What enzyme speeds up cAMP amplification?

What is the advantage of having 2nd messenger?
