Enzymes

Front

What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms without being consumed in the process.

Front

What type of molecule are enzymes?

Back

Enzymes are proteins.

Front

What is the mechanism by which an enzyme and substrate interact?

Back

The lock and key mechanism.

Front

What suffix do most enzymes end with?

Back

-ase

Front

What is the enzyme-substrate complex?

Back

The enzyme-substrate complex is the intermediate formed when an enzyme binds to its substrate.

Front

What is the active site of an enzyme?

Back

The active site is the specific region of an enzyme where the substrate binds.

Front

What role do enzymes play in biological reactions?

Back

Enzymes lower the activation energy required for reactions, thus increasing the rate of the reaction.

Front

Can enzymes be reused?

Back

Yes, enzymes can be reused multiple times as they are not consumed in the reaction.

Front

What factors can affect enzyme activity?

Back

Temperature, pH, and substrate concentration can all affect enzyme activity.

Front

What is a substrate?

Back

A substrate is the reactant molecule upon which an enzyme acts.
