So in this question, we are just looking at the very basic mechanism of your classic enzymes.
00:07
Obviously, we know that there are hundreds of enzymes throughout our body, and enzymes are a key player in any sort of chemical reaction.
00:18
So enzymes, thus, are very specific, unique, but very critical to carry out normal cellular functions.
00:26
And we also know that enzymes work by lowering, the activation energy of a chemical reaction, which allows the reaction to proceed a lot faster.
00:37
So essentially you're going to be able to generate a lot more product, a lot more quicker, and these reactions are going to be more effective and efficient, which overall is going to benefit the cell.
00:49
So when we're looking at just kind of a generalized schematic, sequential view of the mechanism of enzymes, like i said, i'm just giving kind of the very basic here but this goes for all enzymes.
01:02
It's going to occur in three main steps.
01:05
So i have our whiteboard split into these three main steps and i have our enzyme piece drawn in each one.
01:13
So we're going to be looking at the same enzyme and we're just going to follow it through.
01:18
So i already drew that in.
01:22
So when we have our enzyme within our cell, our enzyme is going to seek out a specific substrate.
01:31
And our substrate can be any sort of molecule, usually some sort of steroid or hormone, something like that, some sort of neurotransmitter.
01:41
So when our substrate comes into contact with our enzyme, and a lot of the times our substrates are going to be called multi -complex substrates, and that's because a lot of the times when they are biting to an enzyme, more than one is going to be be needed.
02:01
So for example, i'm going to use green to represent our substrate...
