Enzymes

Front

What is a substance called if it speeds up a chemical reaction?

Back

Catalyst

Front

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

Back

Active site

Front

What do we call the molecule upon which an enzyme acts?

Back

Substrate

Front

What is the term for the complex formed when an enzyme binds to its substrate?

Back

Enzyme-substrate complex

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 the optimum pH for most enzymes?

Back

Most enzymes have an optimum pH around neutral (pH 7), but this can vary.

Front

What happens to enzyme activity as temperature increases?

Back

Enzyme activity typically increases with temperature up to a certain point, after which it may denature.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape due to extreme conditions, rendering it inactive.

Front

What are products in a chemical reaction involving enzymes?

Back

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

Front

How do competitive inhibitors affect enzyme activity?

Back

Competitive inhibitors bind to the active site of an enzyme, preventing the substrate from binding.
