General Properties
• Catalysts
• Protein
• Specific
• Reversible - can catalyse the reaction in both directions
• Denatured by high temperature and change in pH
• Rate of action affected by temperature and pH
Denaturation because most enzymes are proteins is dependent on maintaining the proper three dimensional conformation. Specificity occurs in the special site where the reactants bind and react to form the products. Regulations are a cell does not always want an enzyme to be active.
An enzyme capable of hydrolyzing 4-methylumbelliferyl phenylphosphonate to 4-methylumbelliferone and phenylphosphonic acid has been detected in human serum. It has a Km value of1.72 x 10(-4) mol/L, has an optimum pH of 8.8-9.1 in Tris buffer, and shows maximum activity at 60 degrees C (30 min). The enzymic activity can be inhibited by Na3PO4, EDTA, and cysteine. We saw no effect of CuSO4, adenosine, thymidine, NaN3, diethyl p-nitrophenyl phosphate, p-chloromercuribenzoate, isopropyl fluorophosphate, or eserine on the enzymic activity. The enzyme cannot hydrolyze substrates ofphosphodiesterase I or alkaline phosphatase. The enzyme is considered a phosphonate esterase.
That they are able to facilitate the catalyzation of chemical reactions by lowering the activation energy of those reactions without being changed themselves.
Re sable
Answer:on a general basis the purity of an enzyme can be described as the degree of amount of enzyme required to catalyze a specific reactionamount of enzyme being inversely proportional to purity
An enzyme is one kind of protein that can catalyze a specific reaction whereas a regulatory enzyme is the enzyme which can regulate a series of reaction which undergo in the living organism. So we can say every enzyme is not a regulatory one but the regulatory enzymes are obviously a special kind of enzyme.
The type of molecule that is an enzyme is a protein molecule.
Catalysts are compounds that change the speed of chemical reactions. An enzyme is a protein and also a catalyst. So an enzyme can be a catalyst, but a catalyst can't be an enzyme.
The shape allows the enzyme to carry out specific chemical reactions.
example of ligase enzyme
they are more specific and the remain unchang after the completion of the reaction

When it has the potential to facilitate a chemical reaction; to make it faster. The structure of enzyme-proteins can accelerate a chemical reaction by bringing reactants together by its binding, confinement properties, among others. Structure can indeed easily code for function.
The enzymes ability to stretch reactants and move them towards a transition state
It's a chemical or more precisely a biochemical, some may have enzymatic activity but surely no hormonal and certainly no pathogenic properties!
The enzyme is inactive at this point. New enzyme must be added to regain enzyme activity
in an enzyme-substrate complex, the enzyme acts on the substrate .
An enzyme is a protein
Malt diastase is an enzyme with carbohydrolytic properties. It has the ability to break down polysaccharides. It is used in relieving flatulence and in treatment of constipation. It is also beneficial in treating abdominal discomfort.
The place where the substrate and the enzyme meet to allow the enzyme to function.
