Term
|
Definition
| ligands attatch to these proteins to initiate a signal transduction pathway |
|
|
Term
|
Definition
| these hormones can't get through the membrane of cells so they must attatch to receptor proteins in order to effect various cells |

|
Term
|
Definition

|
|
Term
|
Definition

|
|
Term
|
Definition
| proteins within the membrane of cells which ligands attatch to |
|
|
Term
|
Definition
| released by the G-protein once a ligand has attatched to it and then travels to adenylyl cyclase |
|
|
Term
| Signal Transduction Cascades |
|
Definition
| intracellular signal transductions that typically amplify messages, producing multiple intracellular signals for every receptor that is activated |
|
|
Term
|
Definition
| common secondary messangers, produced by the loss of two phosphate groups of ATP and a catalytic portion |
|

|
|
Term
|
Definition
| consists of two catalytic and two regulatory subunits which is bound to by cAMP on the two regulatory subunits to release the catalytic portions |

|
Term
|
Definition
| targets adenylyl cyclase and blocks signal transduction pathways |
