Carbonic acid occurs naturally in the body and performs important regulatory functions.

Explanation: Carbonic acid ( ) is an acid formed from the carbon dioxide present in the body. It is also known as the respiratory acid as it helps in the transport of carbon dioxide in the body.

With the help of enzyme Carbonic Anhydrase, carbon dioxide is converted into carbonic acid. This acid is an unstable intermediate which gets dissociated into bicarbonate ions ( ) and ions. immediatley.

Therefore, Carbonic acid performs important regulatory functions in the body.
