2. Why do we continue to use extra oxygen after exercise?
3. If someone has a problem with their sympathetic nervous system
having depressed (insufficient) activity, how would this affect their
exercise capacity? What would be different about their circulatory
and respiratory system responses to exercise?
What is the biophysical reason that myoglobin (as opposed to hemoglobin) could never play the role of the oxygen transport system in the human body?
1.
It binds oxygen too tightly
2.
It binds oxygen too weakly
3.
It binds oxygen too slowly
4.
It does not bind oxygen cooperatively
Interpret your data in Graph 1 (Image of Graph 1 attached); What does your data tell you about the effect of temperature on: a) opercular movements in goldfish? AND b) gas exchange in goldfish?
Why can data from the control fish be used as a standard for comparing opercular movements in the experimental fish?

According to the data, after the oxidizing agent (K6[FeCN6]) was added, the absorption of oxidized metmyoglobin was recorded as 0.76 which is higher than oxy-Myoglobin 0.120. What does this indicates???? what does it means????? 2.However, when reducing reagent was added, the absorption of oxymyoglobin is 0.783 which is higher than 0.100 of metmyoglobin.Why is this significant? 3.can this data help to indicates that oxymyoglobin preferred bright red color. Metmyoglobin prefered brown color, and is more susceptible than oxymyoglobin to oxidation?arrow_forward

One summer in college he gets a job as a field biologist in the Colorado Rockies (elevation 7500 ft. above sea level). The first week he is in Colorado he experiences altitude sickness from the change in atmosphere. Altitude sickness is characterized by fatigue and shortness of breath as a result of the thinner air which contains less oxygen. a. How does Andrew's fatigue and shortness of breath relate to the cellular respiration pathway? be. b. What would you expect to find if you test the level of lactic acid in Andrew's blood?

First, the rate and depth of respiration for a resting student were determined. In experiment A, students ran in place for 30 seconds, immediately sat down and relaxed, and then had their respiration rate and depth measured.Experiment B was conducted in the same manner as experiment A, except that the students held their breath while running in place. What differences in respiration would you expect for the two experiments? Explain the basis for your predictions.arrow_forward
