Enzymes

Front

What do enzymes speed up in chemical reactions?

Back

Enzymes speed up reaction rates by lowering the activation energy.

Front

What are enzymes primarily made of?

Back

Enzymes are primarily made of proteins.

Front

What is the term for the specific region on an enzyme where the substrate binds?

Back

Active site.

Front

What is the term for the molecule that an enzyme acts upon?

Back

Substrate.

Front

What happens to enzymes when they are exposed to high temperatures?

Back

The shapes of the enzymes are altered, a process known as denaturation.

Front

What is the role of enzymes in biological reactions?

Back

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

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process where the enzyme's structure is altered, affecting its function.

Front

Can enzymes be reused after a reaction?

Back

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

Front

What factors can affect enzyme activity?

Back

Factors include temperature, pH, and substrate concentration.

Front

What is the effect of pH on enzyme activity?

Back

Each enzyme has an optimal pH range; deviations can lead to decreased activity or denaturation.
