Enzymes

Front

What is the active site of an enzyme?

Back

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

Front

What is an enzyme-substrate complex?

Back

An enzyme-substrate complex is the temporary molecule formed when an enzyme comes into perfect contact with its substrate.

Front

How do enzymes affect activation energy?

Back

Enzymes decrease the activation energy required for a chemical reaction to occur, making it easier for the reaction to proceed.

Front

Can enzymes be used multiple times?

Back

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

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions in biological systems without being consumed.

Front

What happens to enzymes at high temperatures?

Back

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

Front

What is substrate specificity in enzymes?

Back

Substrate specificity refers to the ability of an enzyme to choose exact substrate molecules to bind and catalyze a reaction.

Front

What is the difference between competitive and non-competitive inhibition?

Back

Competitive inhibition occurs when an inhibitor competes with the substrate for the active site, while non-competitive inhibition occurs when an inhibitor binds to a different part of the enzyme.

Front

What is the effect of pH on enzyme activity?

Back

Each enzyme has an optimal pH range; deviations from this range can reduce enzyme activity or denature the enzyme.

Front

What are products in an enzyme-catalyzed reaction?

Back

Products are the substances that are formed as a result of the enzyme-catalyzed reaction.
