People have been known to do things to increase the amount of hemoglobin, the oxygen transport molecule, in their bloodstream. From a cell's point of view, what would be the advantage of increased oxygen levels during intense exercise?
Which of the following conditions DOES NOT cause a “right shift” in the oxygen dissociation curve? A) A decrease in pH (increase in [H +]). B) An increase in [2,3-Di-Phosphoglycerate] (2-3, DPG concentration). C) An increase in body temperature. D) A decrease in oxygen concentration. E) An increase in CO2 concentration
Hello, A depressed person attempts to commit suicide by taking a whole bottle of sleeping pills. The pills cause a drastic decrease in the pH. The patient starts having breathing difficulties because the thick and thin filaments within the respiratory muscles are breaking down. Please explain why their respiratory muscles are breaking down? Thank You
After spending a day or more at high altitude (with an oxygen partial pressure of 75 torr), the concentration of 2,3- bisphosphoglycerate (2,3-BPG) in red blood cells increases. What effect would an increased concentration of 2,3-BPG have on the oxygen-binding curve for hemoglobin? Why would this adaptation be beneficial for functioning well at high altitude?
Carbon dioxide is produced during aerobic respiration of animals but is not completely removed from the body. What then is its role in homeostasis?
Why is oxygen important for animals to survive?
Hello, A depressed person attempts to commit suicide by taking a whole bottle of sleeping pills. The pills cause a drastic decrease in the pH. The patient starts having breathing difficulties because the thick and thin filaments within the respiratory muscles are breaking down. Explain in depth the correlation between the person’s pH and why their respiratory muscles are breaking down. Thank you!
Test Your Understanding 13. INTEREPT DATA Look at Figure 46-10b. How would strenuous muscle activity affect the oxygenhemoglobin dissociation curve? (Hint: How does muscular activity affect pH? See Chapter 40 if you need to review this concept.) Figure 46-10 Oxygen-hemoglobin dissociation curves
What is the difference between respiration and aerobic cellular respiration?
We inhale oxygen when we breathe and exhale carbon dioxide. What is the oxygen used for and where does the carbon dioxide come from?
13. There are several ways to measure cellular respiration experimentally. For example, CO2 and O2 gas sensors measure changes over time in the concentration of carbon dioxide or oxygen, respectively. Design two experiments to test the effects of changing two different variables or conditions (one per experiment) on the respiration of research organism of your choice.
Test Your Understanding 1. Which of the following is a benefit of gas exchange in air compared with gas exchange in water?
