Question

Which three statements accurately describe the blood buffering system in humans? The blood buffering system depends on the ionization of H2PO–4 . 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+ . The blood buffering system utilizes the H2CO3 / HCO–3 conjugate acid/base pair. The blood buffering system utilizes the acetic acid/acetate conjugate acid/base pair. The blood buffering system maintains the pH of blood near 7.4.

Answer 1

1) The blood buffering system maintains the pH of blood near 7.4, as long as it must be quite neutral to favor metabolism.

2) The blood buffering system uses the H2CO3 / HCO–3 conjugate acid/base pair because such relationship in the Henderson–Hasselbalch equation is roughly one.

3) It is facilitated by the enzyme carbonic anhydrase, which interconverts carbon dioxide and water to carbonic acid.

Step-by-step explanation:

Hello,

In this case, the three statements accurately describing the blood buffering system in humans are:

1) The blood buffering system maintains the pH of blood near 7.4, as long as it must be quite neutral to favor metabolism.

2) The blood buffering system uses the H2CO3 / HCO–3 conjugate acid/base pair because such relationship in the Henderson–Hasselbalch equation is roughly one.

3) It is facilitated by the enzyme carbonic anhydrase, which interconverts carbon dioxide and water to carbonic acid as follows:

`CO_2(aq) + H_2O(l) <--> H^+(aq) + HCO_3^-(aq)`

Best regards.

Answer 2

The 3 statements that accurately describe the blood buffering system in humans are listed below.

Step-by-step explanation:

1 The buffering system is facilitated by the enzyme carbonic anhydrase which inter converts carbon dioxide and water to carbonic acid ionizing into bicarbonate and H+.

2 The blood buffering system utilizes H2CO3/HCO3- conjugate acid base pair.Here Here H2CO3 is a conjugate acid whereas HCO3- is a conjugate base.

3 The blood buffering system maintain the pH of the blood near 7.4.
