Answer:

The tissue cells

Explanation:

I think you mean this

[tex]H^{+}+HCO^{3} ^{-} <--> H_{2}CO_{3}[/tex]

It all starts from Carbondioxide. This Carbondioxide is dissolved in the blood and taken by red blood cell and converted into carbonic acid. It then dissociates to form a bicarbonate ion [tex]HCO^{3} ^{-}[/tex] and a hydrogen ion [tex]H^{+}[/tex]

This <--> means that the whole process is reversible. It is a buffer system to maintain the pH in the blood and duodenum. And also to support proper metabolic function.

Answer:the correct option here is C

Explanation:

Ok, the correct equation for the reaction is given below;

H^+ + HCO3^- <------------> H2CO3.

This reaction do occur in the blood in the tissues.

THE REACTION STEPS:

(1). Carbondioxide, CO2 goes into the blood stream and combines with water to form the carbonic acid, H2CO3.

CO2 + H2O <------------------> H2CO3.

Although, this reaction reaction is slow, it is catalyzed by a protein enzyme, carbonic anhydrase in the red blood cells.

(2). The carbonic acid,H2CO3 dissociates into H^+ and HCO3^-

H^+ + HCO3^- <--------------> H2CO3.

The HCO3^- acts as buffer in the blood.

The Carbonic acid is then converted into Carbondioxide back for expulsion in the lungs.
