What are the two routes for long-distance signal delivery in the body?
Expert Solution & Answer
Summary Introduction
To determine: The two routes for long-distance signal delivery taking place in the body.
Introduction: The process of signal transduction helps in transmitting the signals from different parts of the body to the brain and from the brain to different parts of the body. Signal transduction is a highly regulated process that takes place through various proteins and channels.
Explanation of Solution
The two routes that are required for the long-distance delivery of signals are the circulatory system and the nervous system. The circulatory system helps to deliver signals like neurotransmitters, hormones, and other protein molecules through the blood that reaches all the parts of the body from the brain to the lower limbs. Hence, it delivers signals to all the parts of the body, irrespective of their distance.
The nervous system transmits electrical impulses through neurons that can be the longest cells in the body, transmitting electrical impulses from the brain to the toes of the feet. Therefore, both circulatory system and nervous system form the long-distance routes for signal delivery.

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.

- There is currently a H5N1 cattle outbreak in North America. According to the CDC on Feb 26*: "A multistate outbreak of HPAI A(H5N1) bird flu in dairy cows was first reported on March 25, 2024. This is the first time that these bird flu viruses had been found in cows. In the United States, since 2022, USDA has reported HPAI A(H5N1) virus detections in more than 200 mammals." List and describe two mechanisms that could lead to this H5N1 influenza strain evolving to spread in human: Mechanisms 1: Mechanisms 2: For the mutations to results in a human epidered they would need to change how the virus interacts with the human host.
