How sweat gland production and secretion are affected when a person is frightened or nervous. Concept introduction: Sweat glands are a type of exocrine gland. They are the tubular structures of skin that produce sweat. They are involved in the regulation of body temperature. The sweat glands are of two types, namely eccrine or merocrine sweat glands and apocrine sweat glands. Eccrine sweat gland secretes fluid that contains water and sodium chloride into the hair follicle sac. Apocrine sweat gland secretes sweat that consists of proteins and fatty acids directly onto the skin surface.

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
