Hello my dear students.
00:04
The concept given in the question is about the enzyme activity.
00:12
Okay, what is required for us is to tick off or get to know the options which is the right characteristic of the enzyme.
00:26
Let us get into the explanation by or through a suitable image.
00:34
So my dear students, what is enzymes? now enzymes are the bio -catalyst, okay, which fastens a reaction or a rate of reaction without getting consumed in the reaction.
01:05
Okay? so i'll show, i'll tell you what's there in the graph.
01:10
So looking at the definition, you can draw its characteristics saying that it.
01:16
Remains unchanged at the end of the reaction where according to this option c we can say it is right.
01:28
And next thing is what is on addition of extra enzymes or by increasing its concentration, the rate of reaction increases.
01:43
Okay? rate of the reaction increases.
01:46
This is pertaining when there is still availability of the substrate.
01:52
If it is over then the rate of reaction dips.
01:55
Okay.
01:58
So according to this option a is also correct.
02:02
Now one more thing very very importantly is when the presence of enzymes the activation energy is lowered or it lowers the activation energy.
02:13
Now what is this activation energy if you see it is the maximum energy which has to be displayed or which has to be present by the reactants to undergo? a reaction.
02:25
It is an energy barrier.
02:27
For each reaction, the energy barrier or activation energy is different.
02:32
If you see in this graph, if for this reactants, carbohydrates undergoing breakdown in the presence of oxygen, the activation energy barrier is somewhere here.
02:44
Now, without the enzymes present, this reactant should have so much of activation energy in order to undergo the reaction.
02:53
So that is what it says.
02:54
Overall, all energy released during the reaction.
02:57
So in this reaction, the energy is released.
03:01
That is what they say here...
