Explanation The small tears in the blood vessels are closed/plugged by platelets in order to stop bleeding or blood loss. Platelets immediately accumulate in large quantities at the site of vessel damage. Platelets expose collagen fibers at the edges of damage after which they secret several types of products. Certain products signal other platelets while others cause the vessel to constrict in order to reduce bleeding. Clotting is not a single step process and includes a sequence of events during which platelets play major role...

Summary Introduction

To review:

The detailed functions of platelets.

Introduction:

Platelets are one of the three types of cells that are present in the blood and the other two include erythrocytes and leukocytes. Every type of blood cell in the human body is designated with a different type of function. Red blood cells are the carrier of oxygen while white blood cells are mainly involved in protective functions of the body.

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
