What is the basic structure of an amino acid? What do they look like? - amino group (NH2 or NH3), carboxyl group (COO or COOH), alpha carbon (C), and variable group How do you identify the 3 different types of side chains: non-polar/hydrophobic, polar, and charged? - Non-polar/hydrophobic - end with CH or "can't have" water. Polar - end with OH, SH, or NH. Charged - end with a charge what kinds of bonds do each of the 3 different types of side chains make? - ionic, hydrophobic/nonpolar, ...

Ultimate AP Biology Exam Review Questions with Verified Answers Compare and contrast transpiration and translocation. What is the difference between xylem and phloem? Tranpspiration is the loss of water vapor from the surgace of a plant through the stomata. Translocation is the channeling of the sugar through the phloem.
