Textbook Question
Chapter 9.3, Problem 6CYU
MAKING CONNECTIONS Consider a phosphorus atom that is part of the membrane of the sarcoplasmic reticulum in the biceps muscle of your arm. Using the levels of structural organization (described in Chapter 1), the chapter The Human Body: An Orientation), name in order the structure that corresponds to each level of organization. Begin at the atomic level (the phosphorus atom) and end at the organ system level.

Learning Objectives
Identify a peptide bond, the N-terminus (amino-terminus) and C- terminus (carboxyl-terminus) of a polypeptide in a series of linked amino acids.
Describe the four levels of protein structure (primary, secondary, tertiary, and quaternary), what types of bonding interactions hold each level together, and how a protein’s structure relates to its cellular function.
Link the chemical structures of amino acid R groups to the types of interactions they could form in the folded structure of a protein.
Hypothesize the likely consequence of environmental conditions on the folded structure.
Recognize secondary structure elements when proteins are represented in different ways (e.g. ball-and-stick structures, ribbon diagrams).
Define these terms: enzyme, enzyme activity, active site, substrate, enzyme substrate complex, product, denature.
Explain with molecular detail how some conditions affect enzyme activity.
