What role does the tertiary structure of a protein play in determining its function and interactions within a biological system?
The tertiary structure of a protein, which refers to its three-dimensional shape, is crucial in determining its function and interactions within a biological system. This structure allows the protein to form specific binding sites that can interact with other molecules, such as enzymes or receptors. Changes in the tertiary structure can alter the protein's function and ability to interact with other molecules, impacting its role in biological processes.
