Question
Chapter 18, Problem 25RQ
a.
Summary Introduction
To determine: The percent saturation of the Bzork’s oxygen-carrying molecule in the blood at an exercising cell and at the alveoli.
Introduction: The oxygen transportation to various organs takes place by the circulatory system (blood). Blood contains a protein called hemoglobin that carries the oxygen to different parts of the body.
b
Summary Introduction
To determine: The conclusion for the oxygen requirement by Bzork during exercise and during normal activity.
Introduction: The oxygen transportation to various organs takes place by the circulatory system. Blood contains a protein called hemoglobin that carries the oxygen to different parts of the body.

A soccer coach is seeking your advice about using a tank of oxygen on the sidelines so players might breathe from it during time outs or when they come off the field. Provide 3 mechanisms to explain/justify your answer to the coach. Consider the following in your answer.
98% O2 Hb saturation is achieved with each breath. The other way for oxygen to be carried to muscle would be dissolved in blood. This is minimal and still doesn’t affect Hb saturation
Pulmonary ventilation is not considered to limit aerobic capacity
A higher breathing rate actually helps to eliminate CO2 and therefore raise pH
CO2 transport in blood also involves buffering H+ forming bicarbonate HCO3. On exhalation the H disassociates and forms water – again helping to maintain pH
Figure 6 shows the binding of oxygen to myoglobin and haemoglobin (Y-axis: Fraction
saturation) when they are exposed to various partial pressures of oxygen (X-axis: pO2).

Based on Figure 6, explain the differences between the functions performed by
myoglobin and haemoglobin.
Fraction saturation
Explain what caused the trend that you observed when you plotted duration of voluntary apnea as a function of alveolar minute volume. Note you need to EXPLAIN why you saw the pattern, not just repeat the answer to the question above!

In the study, the results of which are shown in the Figure, mice were exposed to tobacco smoke or normal air. The amount of lung tissue damage caused by each exposure was measured in mice that were given tomato juice (1) or water (2). To estimate the destruction of the alveolar wall, a destructive index (DI) was calculated from histological slides of the lung. All lungs will show some level of damage, but a DI above 10% is considered significant destruction. What is the effect of tobacco smoke on the lung tissue in these mice? Source: Based on S.
