STAAR Review: Enzymes and Biomolecules

Front

What is the optimal pH for enzyme activity?

Back

Enzymes typically work best at a specific pH, often around pH 7 for many enzymes.

Front

What are proteins made of?

Back

Proteins are made of monomers called amino acids.

Front

Where do substrates bind on an enzyme?

Back

Substrates bind at the active site of an enzyme.

Front

What type of biomolecule are enzymes classified as?

Back

Enzymes are classified as proteins.

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes act as biological catalysts that speed up chemical reactions.

Front

What is a substrate in the context of enzymes?

Back

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

Front

What is the active site of an enzyme?

Back

The active site is the region on the enzyme where the substrate binds.

Front

What happens to enzymes after a reaction?

Back

Enzymes are not consumed in the reaction and can be reused.

Front

What factors can affect enzyme activity?

Back

Factors include temperature, pH, and substrate concentration.

Front

What is denaturation in relation to enzymes?

Back

Denaturation is the process where an enzyme loses its shape and function due to extreme conditions.
