Correct answer is (b) CO 2+ H 2 O stackrel text Carboinic anhydrase leftharpoons H 2 CO 3 stackrel text Carbonic anhydrase leftharpoons H ++ HCO 3-

Q. Which of the following equations is correct?

$C O_{2} \to H_{2} C O_{3} \to H C O_{3}^{-} + H^{+}$

$C O_{2} + H_{2} O ⇌ Carboinic anhydrase H_{2} C O_{3} ⇌ Carbonic anhydrase H^{+} + H C O_{3}^{-}$

$C O_{2} + H_{2} O \to C H_{4} + 2 O_{2}$

$C O_{2} + H_{2} O ⇌ CO + H_{2} O_{2}$

Correct answer is (b) $C O_{2} + H_{2} O ⇌ Carboinic anhydrase H_{2} C O_{3} ⇌ Carbonic anhydrase H^{+} + H C O_{3}^{-}$

Q. Which of the following equations is correct?

CO2​→H2​CO3​→HCO3−​+H+

CO2​+H2​O⇌ Carboinic anhydrase ​H2​CO3​⇌ Carbonic anhydrase ​H++HCO3−​

CO2​+H2​O→CH4​+2O2​

CO2​+H2​O⇌CO+H2​O2​

Correct answer is (b) CO2​+H2​O⇌ Carboinic anhydrase ​H2​CO3​⇌ Carbonic anhydrase ​H++HCO3−​

$C O_{2} \to H_{2} C O_{3} \to H C O_{3}^{-} + H^{+}$

$C O_{2} + H_{2} O ⇌ Carboinic anhydrase H_{2} C O_{3} ⇌ Carbonic anhydrase H^{+} + H C O_{3}^{-}$

$C O_{2} + H_{2} O \to C H_{4} + 2 O_{2}$

$C O_{2} + H_{2} O ⇌ CO + H_{2} O_{2}$

Correct answer is (b) $C O_{2} + H_{2} O ⇌ Carboinic anhydrase H_{2} C O_{3} ⇌ Carbonic anhydrase H^{+} + H C O_{3}^{-}$
