Question

Select the True statement(s) for this equation: CO_2 + H_2 O rightarrow H_2 CO_3 rightarrow H^+ + HCO^-_3 This is the main way carbon dioxide is transported In the tissues, the reaction happens as written, but in the lungs the reaction is reversed. As this reaction occurs it will make the blood pH decrease This reaction occurs mainly in the plasma. In alveoli where ventilation is inadequate, the PO_2 is _________ causing_____ low, bronchioconstriction low, bronchiodialation low, vasochioconstriction low, vasodialation high, bronchioconstriction

Explanation / Answer

correct answers is

this is the main way of carbondioxide trasported.

REASON

because carbondioxide is transported in the dissolve form in the body.

2nd right option

in the tissue, the reaction happens as written but in lungs reaction is reversed.

EXPLAINATION

as the carbondioxide release as product of cellular respiration it then dissolve in blood. In blood it is converted into carbonic acid on reaction with water .

then it is tranported to lungs in dissolve form and then in lungs this reaction reverses tthat is carbonic acid decomposes to give carbondioxide and water as product.

now this carbondioxide is diffuses to lungs for expellsion.

3rd correct option

this reaction mainly occur in plasma.

EXPLAINATION

carbondioxide is waste product of respiration and its concentration is high in respiring cells.

then haemoglobin is attachted to CO2 then carbondioxide is tranported to lungs for expelsion.

CO2 in plasma ----> CO2 + H2O -----> CARBONIC ACID.
