Proteins and Enzymes

Front

What is the function of an enzyme in a chemical reaction?

Back

An enzyme speeds up a reaction by lowering the activation energy.

Front

What is the monomer of proteins?

Back

Amino acids are the monomers of proteins.

Front

What is an enzyme?

Back

An enzyme is a biological catalyst that speeds up chemical reactions in living organisms.

Front

What is a polypeptide chain?

Back

A polypeptide chain is a sequence of amino acids linked together by peptide bonds.

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 is a substrate?

Back

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

Front

What are products in a chemical reaction?

Back

Products are the substances that are formed as a result of a chemical reaction.

Front

How do enzymes affect the rate of a reaction?

Back

Enzymes increase the rate of a reaction by lowering the activation energy required.

Front

What is the role of amino acids in proteins?

Back

Amino acids are the building blocks of proteins, determining their structure and function.

Front

What is denaturation in proteins?

Back

Denaturation is the process where proteins lose their structure and function due to external stress, such as heat or pH changes.
