"Lock and Key" model of enzyme action illustrates that a particular enzyme molecule
Open in App
Solution
The correct option is C Interacts with specific type of substrate molecule
Enzymes are specific in their action. The enzymes combine with the substrate to form an enzyme-substrate complex. Part of an enzyme where substrate molecules get attached is known as an active site. On attachment to the active site, the substrate is changed into the product. The active site has a residue which helps in the attachment of substrate. The substrate molecules form a temporary bond with the enzyme at the active site. The size and shape of the substrate determine its attachment to the active site. Lock and key model states that the specific substrate attaches to an active site like a key fits in a specific lock.So, the correct answer is option C.
