The structure of a protein dietates the partners with which it can interact. Therefore, the structure of a protein is directly related to its The contours of a protein determine the that its interaction partner must have, whereas the surface chemistry of a protein determines the kinds of chemical interactions that the protein will make with its interaction partner (e.g. Coulombic interactions or) Therefore, a protein will only bind to molecules that have the appropriate shape and chemistry (i.e. only those that are the protein). Biochemists talk about protein structure at four distinct levels: primary, secondary, tertiary and quaternary structure. Below are depictions of each of these levels of protein structure. For each image, match the term and the written description of the level of protein structure that the image depicts. Drag the appropriate items to their respective bins.
