Some g protein-coupled receptors are sensitve to hormones such as angiotensin ii and oxytocin, and act through compounds such as phospholipase c and ip3. (a) complete the flowchart showing the cleavage of a membrane lipid to form compounds that ultimately cause the phosphorylation of specific proteins. the abbreviations used are phosphatidylinositol 4,5-bisphosphate, pip2; protein kinase c, pkc; diacylglycerol, dag; and inositol 1 ,4,5-triphosphate, ip3; phospholipase c, plc. b)which of the compounds can be considered second messengers? 1-dag 2-pkc 3-ser 4-ip3 5-pip2 6-plc 7-ca2+ !

In 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? in 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? staphylococcus aureus bacteria that were able to synthesize cell walls using a protein that was not affected by methicillin survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, some bacteria began to synthesize cell walls using a protein that was not affected by methicillin. these bacteria survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, bacterial populations gradually began to synthesize cell walls using a protein that was not affected by methicillin.
