Enzymes

Front

What are enzymes?

Back

Enzymes are proteins that act as catalysts to speed up chemical reactions in biological systems.

Front

What is the primary function of enzymes?

Back

The primary function of enzymes is to lower the activation energy of a reaction, making it easier for the reaction to occur.

Front

What happens to enzymes at high temperatures?

Back

Enzymes can denature (change shape) at high temperatures, which can lead to a loss of function.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process where an enzyme loses its three-dimensional structure, affecting its ability to function.

Front

What are the building blocks of enzymes?

Back

Enzymes are made up of amino acids, which are the building blocks of proteins.

Front

Can enzymes be reused after a reaction?

Back

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

Front

What is the effect of pH on enzyme activity?

Back

Extreme pH levels can denature enzymes, affecting their activity and function.

Front

What is an active site?

Back

The active site is the specific region on an enzyme where substrate molecules bind and undergo a chemical reaction.

Front

What is a substrate in enzyme reactions?

Back

A substrate is the reactant molecule that an enzyme acts upon during a chemical reaction.

Front

What is the lock and key model of enzyme action?

Back

The lock and key model describes how a specific substrate fits into the active site of an enzyme, similar to a key fitting into a lock.
