By stabilizing the transition state and providing an alternative reaction pathway.

Front

What is the difference between saturated and unsaturated fatty acids?

Back

Saturated fatty acids have no double bonds between carbon atoms, while unsaturated fatty acids have one or more double bonds.

Front

What is the significance of the active site of an enzyme?

Back

It is the region where substrate molecules bind and undergo a chemical reaction.
