Here the question says that an enzyme catalyzes the reaction, that is, the a plus b results into the c formation.
00:13
So this is basically the enzymatic reaction which involves the enzyme.
00:20
And enzymes are the bio -catalyst, which spits up the biochemical reaction.
00:26
And here this two, that is a and b, these are.
00:30
The substrates and the c here is the product.
00:36
So when substrate bind with the enzyme there would be a change in its structure and that is known as the conformational change or the structural change.
00:52
That is also can be explained by the lock and key model in which the enzyme will change its shape to bind properly with the substrate molecule and to convert it into the product.
01:05
And regarding the same, if you look at this diagram, which shows this is the substrate molecule.
01:13
This is the enzyme and this is the active site of an enzyme.
01:19
The active site is the site where the substrate binds to the enzyme molecule and enzyme changes its shape slightly as substrate binds.
01:30
So according to the substrate, the enzyme will change its structure of the active side to suitably binds with substrate molecule.
01:39
And this is known as the conformational changes.
01:43
And after then, this is the formation of enzyme substrate complex.
01:47
After that, the enzymes will lower the activation energy of the reaction or of the process.
01:54
And then it will convert this substrate to the products.
01:59
So this is, this both are the products and ultimately this product leave the active side of an enzyme.
02:05
So this is how the biochemical reaction or the enzymatic reaction is going on.
02:10
Now if we look at the first option given here, the first option is the enzyme undergoes a conformational change when bound to a and b...
