Lab Flashcard Enzymes

Front

What is the active site of an enzyme?

Back

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

Front

What suffix do most enzymes end with?

Back

-ase

Front

What is a substrate in the context of enzymes?

Back

A substrate is any substance that is acted upon by an enzyme.

Front

What does specificity mean in relation to enzymes?

Back

Specificity refers to the ability of an enzyme to choose exact substrates from a group of similar chemical molecules.

Front

What is a catalyst?

Back

A catalyst is a substance that speeds up a chemical reaction without being consumed in the process.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts to accelerate chemical reactions in biological systems.

Front

What happens to an enzyme during denaturation?

Back

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

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 the difference between a coenzyme and a substrate?

Back

A coenzyme is a non-protein molecule that assists enzymes, while a substrate is the substance the enzyme acts upon.

Front

Can enzymes be reused after a reaction?

Back

Yes, enzymes can be reused multiple times after catalyzing a reaction.
