Enzymes

Front

What are enzymes?

Back

Enzymes are biological catalysts that speed up chemical reactions in living organisms without being consumed in the process.

Front

What is the active site of an enzyme?

Back

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

Front

What is a substrate?

Back

A substrate is the reactant molecule upon which an enzyme acts.

Front

What do enzymes typically end with?

Back

Enzymes typically end with the suffix '-ase', such as 'lactase' or 'amylase'.

Front

What is the primary function of enzymes?

Back

The primary function of enzymes is to speed up chemical reactions by lowering the activation energy required.

Front

What happens to enzymes at high temperatures?

Back

At high temperatures, enzymes can denature, meaning their shape is altered, which affects their ability to function.

Front

What is denaturation in enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape due to external factors like heat or pH changes.

Front

What is the relationship between enzymes and activation energy?

Back

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

Front

Can enzymes be reused?

Back

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

Front

What factors affect enzyme activity?

Back

Factors that affect enzyme activity include temperature, pH, substrate concentration, and the presence of inhibitors.
