Structure-Function Relationship

The structure-function relationship means that the shape and parts of a biological molecule or system determine how it works. For example, the specific shape of an enzyme allows it to recognize and interact with certain substances. Similarly, the structure of a cell membrane controls what substances can enter or exit. This close connection explains why changes in structure can affect how effectively something functions. Understanding this relationship helps us see how form and purpose are connected in biology, ensuring a clear link between an organism's design and its role.
