11 25 oints AMP activated protein kinase AMPK is an enzyme that is activated by high levels of AMP in cells If levels of AMP are high in cells that means that levels of ATP are low Once active AMPK activates catabolic pathways and inhibits anabolic pathways in the cell Why do you think that is the case Choose the answer that best explains the role of AMPK Multiple Choice By activating catabolic pathways AMPK provides a mechanism to activate exergonic pathways which is important if AMP levels are high in the cell O High levels of AMP Indicate that there is a high amount of energy stored in the cell thus activating catabolic pathways and inhibiting anabolic pathways are mechanisms to use stored energy By inhibiting anabolic pathways AMPK provides a mechanism to generate heat for the cell which is important if AMP levels are high in the cell Activating catabolic pathways and inhibiting anabolic pathways will ultimately lead to higher consumption of ATP which is important if AMP levels are high in the cell

13 Tacrolimus FK 506 is a drug that inhibits an enzyme called calcineurin Calcineurin is a protein phosphatase This is an enzyme that dephosphorylates removes phosphate groups from proteins When added to cells tacrolimus can inhibit the dephosphorylation of a protein called NFAT but it cannot prevent the dephosphorylation of a protein called CDK1 What is the most likely explanation for this finding Multiple Choice Tacrolimus is a competitive inhibitor of calcineurin for NFAT and CDK11 O Calcineurin requires an additional cofactor to dephosphorylate NFAT O Tacrolimus changes the optimum pH for calcineurin NFAT is a substrate of calcineurin but CDK1 is not
