Biomolecules and Enzymes Review

Front

What is a biomolecule?

Back

A biomolecule is a large molecule that is essential for life, including proteins, nucleic acids, carbohydrates, and lipids.

Front

What are the four main types of biomolecules?

Back

The four main types of biomolecules are carbohydrates, lipids, proteins, and nucleic acids.

Front

What elements do all biomolecules share?

Back

Carbon, Hydrogen, and Oxygen.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes speed up chemical reactions in cells by lowering the activation energy required.

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 an active site?

Back

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

Front

What is a competitive inhibitor?

Back

A competitive inhibitor is a substance that competes with the substrate for binding to the active site of an enzyme.

Front

What is a non-competitive inhibitor?

Back

A non-competitive inhibitor is a substance that binds to an enzyme at a site other than the active site, reducing the enzyme's activity.

Front

What is the function of amylase?

Back

Amylase is an enzyme that catalyzes the breakdown of starch into sugars.

Front

What is the difference between an enzyme and a substrate?

Back

An enzyme is a catalyst that speeds up reactions, while a substrate is the substance that is transformed during the reaction.
