Question

describe the lock and key theory of enzyme action

Answer 1

Your body requires enzyme reactions as catalysts to maintain life. The action of carbonic andydrase, for example, accelerates the movement of carbon dioxide from body cells into the blood by speedily converting carbon dioxide and water into bicarbonate ions, protons and carbonic acid. The blood transports these chemicals to the lungs, where they transform again so carbon dioxide can be released during respiration. Most of the 200 known enzymes are proteins and require a specific substrate that binds to an active site for the necessary chemical reaction to occur.

Answer 2

Lock and key model is given by Emil fisher in 1890 just like specific key opens a specific lock same is with this model a specific enzyme opens a specific substrate becoz the active site of substrate is a rigid structure it is not flexible
