|
Term
IS ALPHA 1 A Gs, Gi, or Gq? |
|
Definition
Gq. IT IS ACTIVATED AND EXCITIED. IT IS LINKED TO IP2 AND CAUSE AND INCREASE IN INTRACELLULAR CALCIUM. |
|
|
Term
|
Definition
WHEN DISCUSSING ALPHA 1 RECEPTOR, SINCE IT IS A Gq, WE TALK ABOUT NOREPI SINCE IT IS AN ADRENERGIC CATECHOLAMINE. WHEN NOREPI BIND TO THE RECEPTOR, IT WILL CAUSE A CONFORMATION CHANGE TO IT. THE GDP IS REPLACED BY GTP WHICH DISSOCIATES THE ALPHA SUBUNIT FROM THE BETA AND GAMMA SUBINITS WHICH ARE STATIONARY. THE DISSOCIATION OF THE ALPHA SUBUNIT ALONG WITH THE GTP WILL ATIVATE PHOSPHOLIPASE C. PHOSPHOLIPASE C CLEAVES PIP2 INTO IP3 AND DAG. IP3 WILL TTHEN BIND TO THE RECEPTORS ON THE ER OR ON THE SR CAUSING CALCIUM RELEASE. THE CALCIUM RELEASE IN CONJUNCTION WITH THE DAG ACTIVATES KINASE C WHICH RESULTS IN SOME PHYSIOLOGICAL REACTION. |
|
|
Term
1 MOLECULE OF NOREPI CAN CAUSE ABOUT HOW MANY ENZYMES TO BE ACTIVATED? |
|
Definition
|
|
Term
HOW DOES B1 AND B2 WORK SINCE THEY ARE Gs? |
|
Definition
THEY WORK THE SAME WAY BUT WHEN THE ALPHA SUBUNIT DISSOCIATES IT ACTIVATES ADENYLYL CYCLASE INSTEAD OF PROSPHOLIPAE C. ADENYLYL CYCLASE ACTIVATES CAMP FROM ATP WHICH IS THE SECOND MESSENGER. |
|
|
Term
Gi PROTEIN INCREASE WHAT EFFLUX? |
|
Definition
K. THAT IS WHY IT IS INHIBITORY BECAUSE IT HYPOERPOLARIZES THE CELL. |
|

Term
AN INOTROPIC RECEPTOR REFERS TO WHAT? |
|
Definition
|
|
Term
A METABOTROPIC RECEPTOR REFERS TO WHAT? |
|
Definition
ALPHA AND BETA RECEPTORS. THEY ACT THROUGH SECOND MESSENGERS WHICH IS WHAT METABOTROPIC RECEPTORS ARE. MUSCARINIC RECEPTORS ARE METABOTROPIC. |
