Which of the following enzyme reactions involves formation...

Which of the following enzyme reactions involves formation of an intermediate in which there is a covalent linkage of the enzyme with a portion of the substrate/product? I. HIV Protease II. Enolase (catalyzing interconversion of 2-phosphoglycerate and phosphoenolpyruvate) III. Lysozyme IV. The transpeptidase required for forming the cross links in bacterial cell walls (these enzymes are also called penicillin-binding proteins (PBPs) ΟI III, and IV • I, III, and IV OII O II and III

Transcript

00:01 Based on the given question, we have been asked to recognize the statements which are correct regarding biological catalyst.

00:08 Now, here the right answer that we can choose is 1, 3, 4, 5 and 6 only.

00:21 So, this is the answer that we have chosen.

00:24 Let's see how it comes to the answer.

00:28 So here regarding the statements, the way.

00:32 We say that these are true and false is because let's go on through the statements first.

00:37 The first statement is that enzymes can clasp down on the substrates that enter and bind together or bind to their active site.

00:46 Now this statement is said to be true and here we can say that enzymes, enzymes can clasp substrates in their active site.

01:06 In their active site.

01:13 Now regarding the second statement, when we enter into the second statement, it shows that enzymes can actively migrate towards substrates thereby increasing their reaction rate.

01:26 Now, this statement is said to be false.

01:28 Now, the reason why we say that this statement is false is because enzymes do not migrate towards the substrates.

01:34 So this is the reason that is enzymes do not migrate.

01:40 Do not migrate towards substrate.

01:46 Towards substrate.

01:51 Moving on to the third statement, let's see what is there.

01:55 So the third statement is that enzymes can create an optimal ph for the reaction to occur in their active site.

02:02 Now regarding this we can say that yes, it is a true statement and the reason is that enzymes can create an optimal ph in their active site...
