In the lock and key model of the enzyme, the substrate fits into the active site of the enzyme. So the correct option is C .
What is enzyme function?
Proteins , the building blocks of all living things, make up enzymes. They perform the function of catalysts, which causes biological processes to proceed more quickly than they otherwise would. Simply said, such processes wouldn't take place or would happen too slowly to support life without enzymes. For instance, digestion would not be possible without enzymes.
Enzymes are made up of chains of amino acids , just like all proteins are. Enzymes catalyze the majority of metabolic events in living things, including people, plants, and animals. The functions of these enzymes vary depending on the order of their amino acids. Depending on its three-dimensional structure, namely the active site of the enzyme molecule, each enzyme has a unique activity.
Enzymes are biological entities that catalyze extremely particular biochemical processes; they are not living creatures. Enzymes recognize their specific substrates, lock on to them, convert them, and then move on to the subsequent substrate molecule.
Therefore, in the lock and key model of the enzyme, the substrate fits into the active site of the enzyme. So the correct option is C .
