The main actions of renin-angiotensin-aldosterone pathway. Introduction: The kidney is an important organ of the excretory system, and nephron is the basic structural unit of kidney. The main function of nephron is ultrafiltration. It removes waste products, ions, and excess water from the blood, and returns the required molecules back to the blood. The glomerular filtration rate (GFR) refers to the rate of flow of filtered fluid through the kidney.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for? 3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
