Protein Structure and Functions

Front

What is the primary structure of a protein?

Back

The primary structure of a protein refers to the sequence of amino acids that make up the polypeptide chain.

What are alpha-helices?

Back

Alpha-helices are a type of secondary structure in proteins formed by hydrogen bonds between amino acids, giving a rod-like shape.

Front

What are beta-sheets?

Back

Beta-sheets are a type of secondary structure formed by hydrogen bonds between amino acids in different parts of the polypeptide chain, resulting in a flat, sheet-like shape.

What is the quaternary structure of a protein?

Back

The quaternary structure refers to the arrangement of multiple polypeptide chains into a functional protein complex.

How do enzymes catalyze biochemical reactions?

Back

Enzymes speed up reactions by lowering the activation energy required for the reaction to occur.
