Enzymes

Front

What is an enzyme?

Back

An enzyme is a protein that acts as a catalyst to accelerate chemical reactions in biological systems.

Front

True or False: Every enzyme has an optimal temperature and pH.

Back

True

Front

What is the pH range of a base?

Back

A base has a pH greater than 7.

Front

Can enzymes be reused after a reaction?

Back

Yes, enzymes can be used again and again after catalyzing a reaction.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes lower the activation energy required for reactions, thus speeding up the process.

Front

What factors can affect enzyme activity?

Back

Enzyme activity can be affected by temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is a substrate in the context of enzymes?

Back

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

Front

What is the active site of an enzyme?

Back

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

Front

What is enzyme specificity?

Back

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

Front

What happens to an enzyme when it denatures?

Back

When an enzyme denatures, it loses its three-dimensional structure and, consequently, its functionality.
