A patient is hyperventilating. The "blowing off" of excessive carbondioxide causes a decrease in blood H+ concentration. How can thecarbonic acid buffering system function to correct this imbalance?CO2 + H2O → H2CO3 → H* + HCO3O H2CO3 dissociates to form more H+ and raise pH.O HCO3- binds with H+ to form H2CO3 and raise pH.O H2CO3 dissociates to form more H+ and lower pH.O HCO3- binds with H+ to form H2CO3 and lower pH.O none of the above

Hyperventilation refers to fast and deep breathing. It occurs when CO2 level in blood increases.

A patient is hyperventilating. The "blowing off" of excessive carbon dioxide causes a decrease in blood H+ concentration. How can the carbonic acid buffering system function to correct this imbalance? CO2 + H20 > H2CO3 + H* + HCO3 O H2CO3 dissociates to form more H+ and raise pH. O HCO3- binds with H+ to form H2C03 and raise pH. O H2CO3 dissociates to form more H+ and lower pH. O HCO3- binds with H+ to form H2CO3 and lower pH. none of the above

When travelling high altitude, one of the problem is alkalosis of the blood. Remember the equation for acid balance: CO2 + H2O ⇌ H2CO3 ⇌ HCO3− + H+ If there is a low amount of CO2 outside, then greater CO2 than normal will diffuse out of the lungs. This will cause the blood to become more basic. To counteract the problem, a drug may be taken to both lower the blood pressure and help correct the pH. To do this, it blocks a symporter of HCO3- and Na+ in the proximal tubule of the kidney. Q: How would blocking transport of HCO3- help to lower the pH of the blood?

Below are multiple oxygen binding affinity curves for hemoglobin. The affinity curve for normal hemoglobin in blood is represented by curve "D," at a pH of 7.2 and at a concentration of 5mM BPG and 26 mM CO2. O₂ saturation (%) 100 Answer 1: B Answer 2: [Select] Answer 3: B Answer 4: 80 A 60 1. How would changes to acidity, BPG concentration and CO₂ levels affect the binding affinity curve and p50? lower than Answer 5: E 40 1. BPG concentration is decreased to 3mM: The binding affinity curve would look like B. The p50 would be lower than normal (D). 2. pH is increased to 7.6: The binding affinity curve would look like B. The p50 would be [Select] normal (D). 20 3. CO₂ concentration is increased to 30 mM: The binding affinity curve would look like. [Select] The p50 would be Answer 6: 0 normal (D). II.
