Enzymes

Front

What is a substrate?

Back

A substrate is the reactant molecule upon which an enzyme acts. It fits into the enzyme's active site.

Front

What do substrates turn into after a chemical reaction involving enzymes?

Back

Substrates turn into products after a chemical reaction.

Front

What term describes the fact that each enzyme only works with one specific substrate?

Back

This is called specificity.

Front

What type of biological molecule are enzymes classified as?

Back

Enzymes are classified as proteins.

Front

What suffix do most enzymes end with?

Back

Most enzymes typically end with the suffix -ase.

Front

What is the role of an enzyme in a chemical reaction?

Back

Enzymes act as catalysts, speeding up chemical reactions without being consumed in the process.

Front

What is the active site of an enzyme?

Back

The active site is the region on the enzyme where the substrate binds and the reaction occurs.

Front

How do temperature and pH affect enzyme activity?

Back

Enzymes have optimal temperature and pH ranges; deviations can reduce their activity or denature them.

Front

What is enzyme denaturation?

Back

Denaturation is the process where an enzyme loses its functional shape due to extreme conditions, rendering it inactive.

Front

What is a cofactor in relation to enzymes?

Back

A cofactor is a non-protein molecule that assists enzymes in catalyzing reactions.
