(Redirected from ATAPI). ATA Packet Interface (ATAPI) is a protocol that has been applied to Parallel ATA and Serial ATA that allows a greater variety of devices to be connected to a computer than ATA would allow.ATA was originally designed for, and worked only with hard disks and devices that could emulate them.Redirected from ATAPI).

Anatomy is the study of the structure and relationship between body parts. Physiology is the study of the function of body parts and the body as a whole. Gross (macroscopic) anatomy is the study of body parts visible to the naked eye, such as the heart or bones.
Protein Structure. The three-dimensional geometry of a protein molecule is so important to its function that four levels of structure are used to describe a protein. The first level, or primary structure, is the linear sequence of amino acids that creates the peptide chain.nzymes. Most enzymes are proteins and therefore their function is specific to their structure. Enzymes function as a catalyst to increase the rate of virtually all the chemical reactions that take place in a living system.
