Key Terms

Protein
A molecule made up of amino acids that performs various functions in the body.

Example: Hemoglobin is a protein that carries oxygen in the blood.

Gene Expression
The process by which information from a gene is used to synthesize a functional gene product.

Example: The expression of insulin is regulated by glucose levels.

Transcription Factor
A protein that binds to specific DNA sequences to control the transcription of genetic information.

Example: The protein NF-kB is a transcription factor involved in immune response.

Binding Affinity
The strength of the interaction between a protein and its binding partner.

Example: High binding affinity means the protein binds tightly to its target.

Signal Transduction
The process by which a cell responds to external signals through a series of molecular events.

Example: Hormones like adrenaline trigger signal transduction pathways.

Receptor
A protein that receives and transmits signals from outside the cell.

Example: Insulin receptors help cells take in glucose.
