BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The first model called the lock and key model, proposes that the shape and chemistry of the substrate are complementary to the shape and chemistry of the active site on the enzyme. This means when the substrate enters the active site, it fits perfectly, and the two binds together, forming the enzyme-substrate complex.

Detailed explanation-2: -The shape of an enzyme’s active site is complementary to the shape of its specific substrate or substrates. This means they can fit together.

Detailed explanation-3: -A substrate is a single molecule, or a combination of molecules, that has a complementary shape to the enzyme’s active site. This allows the enzyme and substrate to bind together and form the enzyme–substrate complex.

Detailed explanation-4: -An enzyme’s shape is determined by the sequence of amino acids in its structure, and the bonds which form between the atoms of those molecules. Why do enzymes have different shapes? Different types of enzymes have different shapes and functions because the order and type of amino acids in their structure is different.
