The important distinction between enzyme and protein is that the enzyme is a organic catalyst whereas the protein can contain within the formation of buildings, transportation, catalysis, and regulation of organic processes.
Enzyme and protein are two kinds of biomolecules discovered within the physique, performing vital capabilities of the physique. An enzyme is a kind of protein whereas proteins are one of many 4 kinds of macromolecules discovered within the physique.

What’s an Enzyme
An enzyme is a globular protein that serves as a organic catalyst. It catalyzes numerous organic reactions by decreasing the activation power of the response by finishing up it by various pathways. This in the end will increase the speed of the response. Considerably, enzymes exhibit a excessive specificity to molecules which bind to it. The inactive type of an enzyme is known as the apoenzyme and it’s activated by the binding of a cofactor. The activated enzyme is known as the holoenzyme. Substrates bind to the lively web site of the enzyme.

Most enzymes within the physique work beneath physiological situations together with temperature and pH. At excessive temperatures and unfavorable pH situations, enzymes are inactivated by altering the form of the lively web site. This course of is known as enzyme denaturation. The perform of an enzyme might be regulated in 3 ways:
- By controlling the focus of enzymes by regulating the expression and degradation of enzymes;
- By controlling the supply of the substrate by regulating the manufacturing, compartmentalization, and degradation of the product;
- By controlling the exercise of the enzyme by the binding of inhibitors or covalent modification of the enzyme construction.
The perform of enzymes is important in numerous organic processes of the physique together with metabolism and digestion. Throughout digestion, enzymes secreted by the intestine break down massive molecules into small molecules, that are simply absorbable. Throughout numerous organic processes, enzymes convey two molecules collectively to supply a brand new molecule.
What’s a Protein
A protein is without doubt one of the 4 kinds of organic macromolecule discovered within the physique. It’s made up of a collection of amino acids. The amino acid sequence of a selected protein is decided by the knowledge encoded within the corresponding gene. The method of the manufacturing of protein is known as protein synthesis, which happens by two steps: transcription and translation. The bonds which hyperlink amino acids collectively are the peptide bonds. The synthesized polypeptide chain then kinds both the secondary buildings like alpha helices and beta sheets, tertiary buildings like globular proteins and filamentous proteins or quaternary construction of proteins by coming collectively the protein subunits collectively.
Determine 2: Protein Construction
Proteins carry out numerous capabilities within the physique. They’re concerned within the formation of buildings together with muscle, cartilages, hair, nails, and cell membrane parts. Most globular proteins function enzymes, hormones, and transport proteins within the blood. Different globular proteins known as antibodies function key molecules within the immune system.
Similarities Between Enzyme and Protein
- Enzymes and proteins are two kinds of biomolecules discovered within the physique.
- Each are made up of a collection of amino acids.
- Additionally, they’re expressed with using directions on genes.
Distinction Between Enzyme and Protein
An enzyme refers to a substance produced by a dwelling organism which acts as a catalyst to convey a few particular biochemical response whereas a protein refers to any of a category of nitrogenous natural compounds, which have massive molecules composed of a number of lengthy chains of amino acids and are a necessary a part of all dwelling organisms, particularly as structural parts of physique tissues equivalent to muscle, hair, and so forth., and as enzymes and antibodies. Hene, this explains the essential distinction between enzyme and protein.
Nevertheless, enzymes are a kind of proteins whereas proteins are a kind of macromolecules within the physique.
One other distinction between enzyme and protein is that enzymes are globular proteins whereas proteins are both globular or fibrous proteins.
Enzymes are categorised based mostly on their perform whereas proteins are categorised based mostly on their chemical composition.
The primary perform of enzymes is to catalyze biochemical reactions whereas proteins type buildings, catalyze biochemical reactions, and regulate organic processes. That is one other main distinction between enzyme and protein.
An enzyme is a kind of globular proteins that function organic catalysts. They scale back the activation power of a particular organic response to extend the speed of the response. Alternatively, proteins are one of many important 4 kinds of macromolecules within the physique with each structural and practical roles. They act as enzymes, hormones or antibodies. That is the essential distinction between enzyme and protein.
