For those who did not copy the class data table: use the following generated data- (file did not save:(
Essential knowledge 4.A.1: The subcomponents of biological molecules and their sequence determine the properties of that molecule.
a. Structure and function of polymers are derived from the way their monomers are assembled.
Evidence of student learning is a demonstrated understanding of each of the following:
1. In nucleic acids, biological information is encoded in sequences of nucleotide monomers. Each nucleotide has structural components: a five-carbon sugar (deoxyribose or ribose), a phosphate and a nitrogen base (adenine, thymine, guanine, cytosine or uracil). DNA and RNA differ in function and differ slightly in structure, and these structural differences account for the differing functions. [See also 1.D.1, 2.A.3, 3.A.1]
✘✘ The molecular structure of specific nucleotides is beyond the scope of the course and the AP Exam.
2. In proteins, the specific order of amino acids in a polypeptide (primary structure) interacts with the environment to determine the overall shape of the protein, which also involves secondary tertiary and quaternary structure and, thus, its function. The R group of an amino acid can be categorized by chemical properties (hydrophobic, hydrophilic and ionic), and the interactions of these R groups determine structure and function of that region of the protein. [See also 1.D.1, 2.A.3,
✘✘ The molecular structure of specific amino acids is beyond the scope of the course and the AP Exam.
3. In general, lipids are nonpolar; however, phospholipids exhibit structural properties, with polar regions that interact with other polar molecules such as water, and with nonpolar regions where differences in saturation determine the structure and function of lipids. [See also 1.D.1, 2.A.3, 2. B.1]
✘✘ The molecular structure of specific lipids is beyond the scope of the course and the AP Exam.
4. Carbohydrates are composed of sugar monomers whose structures and bonding with each other by dehydration synthesis determine the properties and functions of the molecules. Illustrative examples include: cellulose versus starch.
✘✘ The molecular structure of specific carbohydrate polymers is beyond the scope of the course and the AP Exam.
5) I will be able to relate the organic molecules to their everyday life, diet and nutrition.
