Complete the following vocabulary exercise relating to the level of structure in proteins. match the words in the left-hand column with the appropriate blank in the sentences in the right-hand column.
1. tertiary structure is achieved when a protein folds into a compact, three-dimensional shape stabilized by interactions between side-chain r groups of amino acids.
2. quaternary structure is the result of two or more protein subunits assembling to form a larger, biologically active protein complex.
3. primary structure is the sequence of amino acids in a protein.
4. secondary structure describes the alpha-helices and beta-sheets that are formed by hydrogen bonding between backbone atoms located near each other in the polypeptide chain.

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.
