Gradebook () 2/9/2015 12:00 PM7.4/10 () 12/8/2015 08:45 PM Map Which three of the following statements accurately describe the blood bufering system in humans? The blood buering system maintains the pH of blood near 7.4. depends on the ionization or H2PO2 lizes the acetic acidiacetate cougale acid base pair. s tacitated by the enzyme carbonic anhydrase, which interconverts carbon dioxide and water to carbonic acid (ionizes into bicarbonate and H) utilizes the H2COyHCOS corugate acidbase pair. regulates the blood pH at 7.4 +. one pH unit.

Explanation / Answer

we know that

The body's chemical buffer system consists of three individual buffers

1) the carbonate/carbonic acid buffer,

2) the phosphate buffer and

3) the buffering of plasma proteins

phoshphate buffer is very minor

so

there is no acetic acid involved in the buffering system

So

blood utilizes the H2C03/HC03- conjugate acid /base pair

also

we know that

pH of blood is 7.4

also

the pH range should be

6.8 < pH < 7.9

if it is not in this range it leads to death

the carbonic anhydrase present in humans

the major reactions cause by this enzyme is

C02 + H20 ---> HC03- + H+

so

it interconverts carbon dioxide and water to carbonic acid

the correct answers are

1) maintains the pH of blood near 7.4

2) is facilitated by the enzyme carbonic anhydrase

3) utilizes the H2C30 / HC03- coonjugate acid base pair
