Which of the following is NOT a property of enzymes? enzymes are permanently modified during the reactions they catalyze enzymes increase the rate of reactions by reducing their activation energy enzymes are very specific to a certain type of reaction enzymes can bind one or more substrate molecules

00:01 Hi there.

00:02 This question is about enzymes.

00:08 And enzymes are proteins.

00:14 And in living organisms, protein, or these enzymes are biological catalysts.

00:28 And what the term catalyst means is any substance that speeds up a chemical reaction.

00:52 Without being changed itself, it is not actually part of the reaction.

01:15 Okay.

01:16 So now we know what enzymes are.

01:18 So they're proteins and they act as biological catalysts in living things.

01:25 And remember, a catalyst is a substance that's going to speed up the rate of a chemical reaction, but the catalyst itself is not changed.

01:32 So it can speed up the rate of a reaction, and then it will be released, and it can go to the next reaction and act as a catalyst there, again, over and over.

01:41 So let's look for which the following is not a property.

01:45 So we have four statements there.

01:47 The first one says that enzymes are permanently modified during the reactions.

01:53 Well, that one, based upon what we've just been talking about, that first statement is not true.

02:00 It is false.

02:03 Let's look at the other three just to make sure that they are in fact true.

02:07 The second one says that they increase the rate by reducing activation energy...
