Enzymes

Front

What are enzymes?

Back

Enzymes are biological catalysts that speed up chemical reactions in living organisms by lowering the activation energy required for the reaction.

Front

Do enzymes act on many different substrates?

Back

False. Each enzyme typically acts on a specific substrate.

Front

How do enzymes speed up reactions?

Back

Enzymes speed up reactions by lowering the activation energy.

Front

What is the optimal temperature for an enzyme?

Back

The optimal temperature is the temperature at which an enzyme functions most efficiently.

Front

What is the optimal pH for an enzyme?

Back

The optimal pH is the pH level at which an enzyme is most active.

Front

What happens to enzymes at high temperatures?

Back

High temperatures can denature enzymes, altering their shape and rendering them inactive.

Front

What is denaturation in enzymes?

Back

Denaturation is the process where the three-dimensional structure of an enzyme is altered, affecting its function.

Front

What is the active site of an enzyme?

Back

The active site is the specific region of an enzyme where substrates bind and undergo a chemical reaction.

Front

What is the enzyme-substrate complex?

Back

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

Front

What role do enzymes play in metabolism?

Back

Enzymes facilitate metabolic reactions by speeding up the conversion of substrates into products.
