Hint: Study definition of an enzyme as well as of protein and then try to understand the examples to get a clear idea of their definition and their functioning.
Complete answer:
Proteins are,
-Large biomolecules, also called as macromolecules, consisting of 1 or more long chains of amino alkanoic acid depending upon their function. -Proteins perform functions like including catalyzing metabolic reactions, DNA replication, responding to stimuli etc.
-A linear chain of amino alkanoic acid residues is named a polypeptide. -A protein contains a minimum of one long polypeptide. Short polypeptides, containing but 20–30 residues, are commonly called peptides.
Now we will try to understand what exactly an enzyme is and what is its function. Enzymes are,
- Proteins that act as biocatalysts (biological catalysts). Catalysts accelerate chemical reactions.
-The molecules upon which enzymes act are also called substrates, and hence convert the substrate into different molecules called as products.
-The active site of enzymes has a definite shape and the functional group for the binding of reactant molecules.
Hence, we can say that enzymes are stable compounds having an active site as they help break down the substrate into products.
From the above explanation of proteins and enzymes we can conclude the following points:
-Enzymes are proteins.
-Enzymes are bio catalysts having stable configuration and an active site.
So, the correct answer is “Option B”.
Note: We should not get confused with the definition of protein and enzyme as they are not the same, Enzymes are a type of proteins whose prime function is catalysis.
