Textbook Problem

The bulk of the CO 2 produced in the cells is transported to the lungs as

A. H 2 CO 3

B. HCO 3 -

C. CO 2  and H 2 O

D. Carbonic anhydrase

Summary Introduction

Introduction:

The transport of carbon dioxide from the blood to the lungs is mediated through three pathways, that is, carbon dioxide dissolved in solution, carbon dioxide buffered with water as carbonic acid, and carbon dioxide bound to proteins.

Explanation

Justification/explanation for the correct answer:

Option (B) states that bicarbonate ions (HCO3) is the form in which bulk of carbon dioxide is transported to the lungs. It is correct because the carbon dioxide (CO2) from the cells moves into the blood and is buffered with water to give bicarbonate ions (HCO3) and hydrogen ions (H+).

The reaction is as follows

CO2+H2OcarbonicanhydraseHCO3+H+

Hence, option (B) is correct.

Explanation for the incorrect answer:

Option (A) states that H2CO3(carbonic acid) is the form in which bulk of carbon dioxide is transported to the lungs
