7 Under what conditions are enzymes denatured? Is denaturation reversible? Provide an explanation as to why denatured enzymes cannot catalyze chemical reactions. 8 Why doesn't the rate of reaction continue to increase proportionally as the concentration of enzyme increases?

00:01 Hello everyone, let's look at the question.

00:04 So here the question is under what condition enzymes are denatured.

00:10 So here they're asking about denaturation of proteins or denaturation of enzyme, right? denaturation of enzyme.

00:29 Now the denaturation is nothing but to the breaking of certain weak bonds present in enzyme so that the enzyme it loses.

00:42 Structure okay so the this process is known as denaturation of enzyme and not only enzyme the usually the proteins will undergo denaturation denaturation process okay so enzyme is nothing but it's a protein only which acts as biological catalyst okay now so these proteins contains so our enzyme contains certain weak bonds weak bonds such as hydrogen bonds so we know that the proteins are made up of amino acids and so different amino acids so they make bond known as amide bond with each other in a regular order and among these bonds there will be a certain hydrogen bonds which gives its three -dimensional structure okay now so in some way if these bonds are broken so that process is known as denaturation so that the the structure of the enzyme of the protein will be rupture.

01:57 Now so so they are asking so how this denaturation is occurring okay now denaturation can be done either by heating.

02:11 The one way is heating okay so another way is by treating with by treating with alcali any alkali or acid okay or even some urea or using detergents okay so some proteins or the some enzymes can be denatured just by vigorous shaking so these three are different methods for the process of denaturation so the different enzymes are denatured by using different methods okay so this is the answer for the first question the second question the sub question in the first question so this is the let us take as sub question okay in the second one this in a second sub question it is asked that so why denatured enzyme sorry it is so the denaturation process is reversible or not okay so some denaturation process are reversible some are not okay so here some denaturation process are reversible and that is known as re -natureation...
