Question
Chapter 3, Problem 1IA
(a)
Summary Introduction
To determine: The dependent variable in the graph.
Introduction: Hemoglobin is an iron-rich protein present in the blood. This protein acts as a carrier of oxygen in the blood. Oxygen gets attached to the iron-rich protein in the blood and transported to a different part of the body.
(a)
Expert Solution
Explanation of Solution
The given graph shows the effect of pH on the hemoglobin-oxygen binding. Oxygen level represents the X-axis, and the Y-axis represents the percentage of hemoglobin bound to the oxygen. In the given graph, the dependent variable is the percentage of hemoglobin bound O2.
(b)
Summary Introduction
To determine: The pH value that represents the higher concentration of hydrogen ion and also explains their nature.
Introduction: pH value can be defined as hydrogen ion concentration in the solution. The solution which has a higher concentration of hydrogen ion is considered acidic, and a solution with a lower concentration of hydrogen ion is basic.
(b)
Expert Solution
Explanation of Solution
The given graph shows three pH values that have a higher concentration of hydrogen ion are 7.2, 7.4, and 7.6. The solution which has a pH value less than seven are considered acidic, but in the above graph, the values which are the least basic have the higher acidic content. The pH value of 7.2 has a higher concentration of hydrogen ion. The pH value of 7.2 is more acidic than the other two pH values.

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."
