Question

Which of the following equations is correct?

• A. $CO _2 \rightarrow H _2 CO _3 \rightarrow HCO _3^{-}+ H ^{+}$
• B. $CO _2+ H _2 O \stackrel{\text { Carboinic anhydrase }}{\rightleftharpoons} H _2 CO _3 \stackrel{\text { Carbonic anhydrase }}{\rightleftharpoons} H ^{+}+ HCO _3^{-}$
• C. $CO _2+ H _2 O \rightarrow CH _4+2 O _2$
• D. $CO _2+ H _2 O \rightleftharpoons CO + H _2 O _2$

Answer 1

Answer: (B)

Correct answer is (b) $CO _2+ H _2 O \stackrel{\text { Carboinic anhydrase }}{\rightleftharpoons} H _2 CO _3 \stackrel{\text { Carbonic anhydrase }}{\rightleftharpoons} H ^{+}+ HCO _3^{-}$
