Which of these is true about enzymes? a, they increase the rate of reaction by reducing the rate of reverse reactions.
00:08
B, they lower the activation energy barrier.
00:12
C, they make the reaction more exegonic.
00:15
Or d, they change the equilibrium point.
00:19
So, enzymes are catalysts.
00:24
Catalysts.
00:26
And that means that they don't just catalyze the forward reaction.
00:29
They also catalyze the reverse reaction.
00:33
So it's not a.
00:34
If you have a reaction, let's say we have two reactants going to form a product.
00:44
Well, this is only the forward reaction.
00:47
The enzyme auto also will catalyze the reverse reaction.
00:52
So if you want the reaction to always be going forward, then you need some way of shifting the equilibrium, but the enzyme doesn't do that.
01:00
The equilibrium is not changed by the enzyme.
01:03
If perhaps you remove the product by transporting it away, that will change the equilibrium, and that will mean that you keep getting the forward reaction...
