As we know enzyme is a protein that has a tertiary structure. this tertiary structure has ionic disulphide and hydrogen bonds.
enzyme has an active site which attaches to a substrate making it unique.
by denaturating it you brake the bonds that holds this unique structure making it incapable of doing what it does. and for that reason it cant go back to what it was.
take for an example an egg.
before you boil it, the transeperant semi liquid part of it is mainly protein. if you boil it it becomes white and solid. by boiling it you denature the protein.
Now if you leave the egg to cool down you will see that the white solid part of the egg will not become liquid again indicating that proteins doesnt go back to what they were.
and because enzymes are proteins the same thing happens :)
hope it helped :)
cheers :)
What else can I help you with?
What is denaturing And what causes enzyme denaturing?
Enzymes are proteins that help speed up the the rate of chemical reactions in the human body. Enzymes possess a specific shape and this shape fits into the substrate. When an enzyme becomes denatured, it loses its shape and thus it cannot function effectively. Enzymes may become denatured due to high temperatures or changes in the pH.
How does adding an acid to an enzyme reaction effect the enzyme?
it alters the pH of the enzyme denaturing it leaving it unable to carry out it's role effectively or at all
What is the loss of structure of an enzyme due to the increase in temperature called?
The loss of structure of an enzyme due to increased temperature is called denaturation. This process disrupts the enzyme's active site, leading to a loss of its biological activity and function.
What affect would temperature and pH have on the Catalans enzyme?
Just like always, deviating from the desired normal functioning for the enzyme, whether it be in temperature or pH, would result in the enzyme denaturing and therefore being unable to for enzyme substrate complexes, therefore reducing the overall reaction rate.
Does freezing a enzyme affect it?
Yes, freezing an enzyme can affect its activity by denaturing it and changing its structure. Ice crystals can form and disrupt the enzyme's fragile structure, diminishing its function once thawed. It's best to store enzymes at their recommended temperature to maintain their stability and activity.

The distortion of enzyme molecules which occurs at high temperatures is known as?
Denatured
What can affect enzyme activity?
pH Temperature Substrate Concentration non-ideal conditions will ultimately lead to the denaturing of the enzyme
Why does denaturing effect enzyme reactions?
If you denature an enzyme, you do not kill it because it was never alive, but you shut it down. It cannot work any longer and therefore it cannot speed up the reaction. The overall reaction will be slower because there are less enzymes.
What happens if an inhibitor is irreversible?
Irreversible inhibition refers to the inactivation of an enzyme by a tightly, typically covalent, bound inhibitor. The kinetics for irreversible inhibition do not follow competitive or non-competitive kinetics.
Difference between reversible and irreversible inhibitors?
Enzyme inhibitors are molecules that bind to enzymes and decrease their activity. The binding of an inhibitor can stop a substrate from entering the enzyme's active site and/or hinder the enzyme from catalyzing its reaction. Inhibitor binding is either reversible or irreversible. Irreversible inhibitors usually react with the enzyme and change it chemically. These inhibitors modify key amino acid residues needed for enzymatic activity. In contrast, reversible inhibitors bind non-covalently and different types of inhibition are produced depending on whether these inhibitors bind the enzyme, the enzyme-substrate complex, or both.

What substance can be used to stop enzyme reaction?
Denaturing agents such as heat, extreme pH levels, or organic solvents can be used to stop enzyme reactions by altering the enzyme's structure and activity. Additionally, specific enzyme inhibitors can be used to block the active site or prevent substrate binding, effectively stopping the enzymatic reaction.

Yes, freezing an enzyme can affect its activity by denaturing it and changing its structure. Ice crystals can form and disrupt the enzyme's fragile structure, diminishing its function once thawed. It's best to store enzymes at their recommended temperature to maintain their stability and activity.
Why was hcl used to stop the amylase reaction?
HCl was used to stop the amylase reaction by denaturing the enzyme. The acidic environment disrupted the enzyme's structure, rendering it inactive and unable to catalyze the breakdown of starch. This effectively stops the reaction from proceeding further.
