Learn about enzymes, their active sites, and how they catalyze reactions in this comprehensive guide from Khan Academy.

This articles reviews positive and negative cooperativity in enzymes and how this is expressed numerically by the Hill coefficient.

Each type of enzyme typically only reacts with one, or a couple, of substrates. Some enzymes are more specific than others and will only accept one particular substrate.

Zoom into the world of biomolecules as you explore the structure and function of proteins, nucleic acids, carbohydrates, lipids, ATP, and more! Explore some of the ways that these molecules regulate …

The cofactors and coenzymes (organic cofactors) that help enzymes catalyze reactions.

Enzymes catalyze chemical reactions involving the substrate (s). The substrate is transformed into one or more products, which are then released from the active site.

Now since enzymes have unique active sites, we say that enzymes are specific to certain substrates, and by extension certain reactions. But let's dive a little deeper into what happens when enzymes …
