Chapter 14, Problem 60E.4RQ

a.

Summary Introduction

To explain: To identify the organism based on the observation.

Introduction: A 35-year-old female underwent abdominal surgery that involves bowel resection. Following the surgery, she was maintained on a course of intravenous (IV) broad-spectrum antibiotics. She had a fever after three days of the surgery and she also complains of vaginal discomfort. The blood cultures showed the presence of an ovoid cell that reproduces by budding.

b.

Summary Introduction

To explain: whether the identified organism is a part of normal flora in humans.

Introduction: Candida albicans is an opportunistic fungal pathogen. It is the most common fungal species that causes human diseases. It is responsible for causing candidiasis in humans. It causes three types of candidiasis, namely oropharyngeal candidiasis, vulvovaginal candidiasis, and invasive candidiasis.

c.

Summary Introduction

To explain: The way in which the treatment with broad-spectrum antibiotics predisposes the patient to infection with the organism identified.

Introduction: Antibiotics are chemical substances produced by microorganisms that act against other microorganisms. They are used to treat bacterial infections. Broad-spectrum antibiotics are those that act against a large number of disease-causing bacteria.

d.

Summary Introduction

To compare: The effectiveness of hand washing with water, soap, and surgical scrubbing.

Introduction: Human hands come in contact with various objects and surfaces that are contaminated with a wide variety of microbes. Inadequate hand washing is a major transmission vehicle of diseases and infections.

9. Aerobic respiration of one lipid molecule. The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. 18 carbons fatty acids 12 carbons 9 glycerol A. Glycerol is broken down to glyceraldehyde 3-phosphate, a glycolysis intermediate via the following pathway shown in the figure below. Notice this process costs one ATP but generates one FADH2. Continue generating ATP with glyceraldehyde-3-phosphate using the standard pathway and aerobic respiration. glycerol glycerol-3- phosphate…
Normal dive (for diving humans) normal breathing dive normal breathing Oz level CO2 level urgent need to breathe Oz blackout zone high CO2 triggers breathing 6. This diagram shows rates of oxygen depletion and carbon dioxide accumulation in the blood in relation to the levels needed to maintain consciousness and trigger the urgent need to breathe in diving humans. How might the location and slope of the O₂ line differ for diving marine mammals such as whales and dolphins? • How might the location and slope of the CO₂ line differ for diving marine mammals such as whales and dolphins? • • Draw in predicted lines for O2 and CO2, based on your reasoning above. How might the location of the Urgent Need to Breathe line and the O2 Blackout Zone line differ for diving marine mammals? What physiological mechanisms account for each of these differences, resulting in the ability of marine mammals to stay submerged for long periods of time?
