| Questão | Responda |
| How large are they? | 402-407 amino acids long |
| How many membrane spanning loops are there? | 7 |
| Which terminus tends to be glycosylated? | The N-Terminus |
| Is the c-terminus internal or external? | Internal |
| Internal loop 3 & C terminal domain contain... | Serine & threonine for phosphorylation |
| How many types of serpentine receptor are there? | 100 |
| Where does the hormone bind in beta adrenergic receptors? | Below the surface, in the membrane |
| Where is adrenaline formed? | In the Chromaffin cells |
| What causes the release of adrenaline? | Stress or low blood sugar |
| Which of the following is inhibitory in skeletal muscle? | Alpha 2 receptors |
| In adrenaline production, Phenylalanine is converted to --> | Tyrosine |
| Tyrosine is then converted to --> | DOPA |
| DOPA is converted to Dopamine, which is then converted to --> | Adrenaline |
| Which G protein is effected by the alpha 1 receptor? | GQ G-Protein |
| What membrane bound enzyme does the Gq protein activate? | Phospholipase C-beta |
| Phosphlipase C-beta splits Phosphatidanolsitol 4,5 bisphosphate --> | IP3 and diacylglycerol |
| IP3 causes the release of ... | Calcium from the ER |
| The diacylglycerol (and the inorganic ion released by IP3) activates... | Protein Kinase C |
| The ion released by the IP3 also activates... | Calcium dependent kinases i.e. Phosphorylase B Kinase |
| Protein Kinase C and other Ca dependent kinases phosphorylate which residues? | Serine and Threonine |
| What is different between protein kinase C & the Ca dependent kinases? | They phosphorylate at different sites to each other (and cAMP dependent kinases) |
