- Q2Which of the following molecules is a transcription factor?IP3CREBAdenalyl cyclasecAMPVideo120s
- Q3Which of the following molecules passes the nuclear membrane?Regulatory subunit of Adenalyl cyclasecAMPCatalytic subunit of Adenalyl cyclaseCREB120s
- Q4Put the following events in the IP3/DAG pathway in the correct chronological order.ordering://Binding of ligand|1:Activation of G-protein subunit with GTP|2:Dissociation of alpha-subunit of G-protein|3:Activation of phospholipase C-beta|4:Synthesis of IP3 from PIP2|5:Influx of Ca-2+ ions|6: Activation of Protein Kinase C|7:Cellular response|8Video120s
- Q5Both the epinephrine pathway and the IP3/DAG pathway are G-protein coupled receptor pathways, but they differ a lot from eachother. This is due to the fact that epinephrine-receptor is a beta-type receptor, while the IP3/DAG pathway receptor is an alpha-type receptor. Couple the following molecules or effects to their type of receptor.Users sort answers between categoriesSorting300s
- Q6Which of the following is NOT a common second or third messenger in the earlier named G-protein coupled receptors?Ca+None of the abovecAMPIP-3120s
