Document Summary
*interpret macromolecules in relation to their roles and location in cells* Sugars/carbohydrates: why are sugars important in cell; broken down to form atp, plant cells produce sugar through photosynthesis, long term energy storage (long stable chains, quick easy access) Nucleic acids: built from nucleotides, nitrogenous, nucleotide and nucleic acids all relate to nucleic acids but not interchangeable. Macromolecules in a cell: work together; interact with each other, certain types of molecules will be in preferred compartments/ specific locations in cell, determines their relationship. Ch4 bonds are nonpolar covalent because e=0. 35 0. 35<0. 5 therefore nonpolar covalent. If see oxygen, chances are there is a dipole. If non-polar, hydrophobic, likes fat, can be inside membrane, can also be outside the structure of protein unless its in an aqueous environment. Very polar amino acids tend to be hydrophilic; likes water, therefore can be inside the cell in free-floating environment, can be in the folded portion of protein.
