Enzymes

Front

What is a substrate?

Back

A substrate is the substance on which an enzyme acts during a biochemical reaction.

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 is the optimum pH for enzyme activity?

Back

The optimum pH is the pH at which an enzyme is most active and efficient.

Front

How do enzymes affect activation energy?

Back

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

Front

What suffix do most enzymes end with?

Back

Most enzymes typically end with the suffix '-ase'.

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 in the process.

Front

What happens to enzyme activity at extreme pH levels?

Back

Extreme pH levels can denature enzymes, altering their structure and reducing their activity.

Front

What is enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to select and catalyze a specific substrate.

Front

What is a cofactor?

Back

A cofactor is a non-protein chemical compound that is required for the biological activity of some enzymes.

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.
