BIOMOLECULES AND ENZYMES

Detailed explanation-1: -To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme’s substrates.

Detailed explanation-2: -The induced fit model states an substrate binds to an active site and both change shape slightly, creating an ideal fit for catalysis. When an enzyme binds its substrate it forms an enzyme-substrate complex.

Detailed explanation-3: -The enzyme’s active site binds to the substrate. Since enzymes are proteins, this site is composed of a unique combination of amino acid residues (side chains or R groups).

Detailed explanation-4: -An enzyme substrate is the material on which the enzyme operates in biochemistry. The term substrate is sometimes used interchangeably with the term reactant, which refers to the molecule consumed in a chemical reaction.

Detailed explanation-5: -Enzymes bind substrates at key locations in their structure called active sites. They are typically highly specific and only bind certain substrates for certain reactions.
