Hello everyone.
00:01
Today we are going to look at enzymes.
00:05
Enzymes are biological catalysts, and i'm sure you know that catalysts speed up chemical reactions.
00:11
And they do this by providing an alternative pathway with lower activation energy.
00:16
A common mistake people say is that catalysts lower activation energy, that is false.
00:21
They just provide an alternative route with lower activation, thus speeding up the reaction.
00:27
There is the lock and key model which demonstrates the specificity of enzymes.
00:32
How each kind of enzyme can only interact with the specific kinds of molecules, which are called substrates.
00:40
As we can see here, this is a substrate.
00:47
The enzyme can chemically recognize a substrate, bind to it, and change it in some way.
00:53
An enzyme and its substrate interact at a surface on the enzyme.
00:57
This area is called the acticide, as shown over here.
01:04
There are factors of course which impact enzymes and the way that are the way that is the acid...
