IB Biology 2.4 Proteins

Front

What is a protein?

Back

A protein is a large, complex molecule made up of amino acids that performs various functions in the body, including structural support, transport, and catalysis.

Front

How many bases of DNA code for one amino acid?

Back

Three bases of DNA code for one amino acid.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where amino acids are linked together to form polypeptides.

Front

What is a polypeptide?

Back

A polypeptide is a chain of amino acids linked together by peptide bonds, which folds into a functional protein.

Front

What is the genetic code?

Back

The genetic code is the set of rules by which information encoded in genetic material is translated into proteins.

Front

What is a proteome?

Back

A proteome is the entire set of proteins expressed by a genome, and it is unique to each individual.

Front

What are amino acids?

Back

Amino acids are organic compounds that serve as the building blocks of proteins.

Front

What is the function of collagen?

Back

Collagen provides structural support in connective tissues, skin, and bones.

Front

Do all organisms use the same 20 amino acids?

Back

Most organisms use the same 20 amino acids, but there are exceptions.

Front

What is the significance of protein folding?

Back

Protein folding is crucial for the protein's function, as the specific shape determines how it interacts with other molecules.
