- Create a labeled diagram explaining how CO2 moves from cells of the working tissue as HCO3 - in the blood (do not include other ways CO2 moves through the blood). Be sure to include the carbonic anhydrase inside red blood cells and the HCO3 - /Cl- exchanger in your diagram. Write an explanation for your diagram.arrow_forwardWhich three statements accurately describe the blood buffering system in humans? - The blood buffering system utilizes the H2CO3H2CO3/HCO–3HCO3– conjugate acid/base pair. - The blood buffering system utilizes the acetic acid/acetate conjugate acid/base pair. - The blood buffering system is facilitated by the enzyme carbonic anhydrase, which interconverts carbon dioxide and water to carbonic acid, ionizing into bicarbonate and H+H+ . - The blood buffering system maintains the pH of blood near 7.4. - The blood buffering system depends on the ionization of H2PO–4H2PO4– .arrow_forwardMr. Smith breathes 1 liter of air per minute at 22 degrees Celsius; Mr. Jones breaths 1 liter of air per minute at BT.

- What would be the effect of an artificial blood in which the binding of oxygen is not altered by the presence of an acidic pH?arrow_forwardWould you expect the concentration of HCO3 to be higher in blood plasma taken from a systemic artery or a systemic vein?arrow_forwardWhen 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?arrow_forward

This condition is associated with mutations in the genes that control anion exchange proteins, specifically the chloride-bicarbonate exchanger Band 3. Explain how the anion exchange proteins work in the capillaries of normal people's body tissue and discuss how this process might be disrupted in alkalosis patients and lead to these symptoms.arrow_forwardConsider the cigarette smoke contain an average of 450 ppm carbon monoxide.
