The relationship between enzyme structure and function is fundamental to biochemistry. Enzymes are proteins that catalyze biochemical reactions, and their function is directly linked to their specific three-dimensional structure. The active site of an enzyme is uniquely shaped to bind specific substrates, facilitating reactions efficiently. Any alteration in the enzyme’s structure, due to changes in pH, temperature, or mutations, can impact its ability to function, illustrating the importance of protein folding and the precise arrangement of amino acids in maintaining enzymatic activity.
