MMG 201 Study Guide for Exam 2 I have outlined each lecture and let you know which points I think are significant in order to perform well on the exam. If you have any questions, please email Dr. Jackson, Dr. Herring, or me Additional resources for review: 1. Textbook by Brock is on reserve at the library in BPS. It can be checked out for two hours. Many of the figures Dr. Herring included in her lecture are from this textbook. If you are confused about the picture, reference the captions from this textbook. 2. Review Session by Rachel Sheridan Monday 6:00 pm in 1415 BPS 3. Lecture 2/26 is a designated review and will include *review clicker questions for points! Please bring specific questions to the review to facilitate discussion. PREVIOUS EXAM Dr. Jackson + Dr. Herring have mentioned that they may include questions from Exam One on the upcoming Exam Two. If you do not understand why your answer was wrong and/or why the selected answer was correct… ASK! LECTURE 1/31 R: Detailed look at Cell Walls Reference Rachel’s Review Week 3 for visuals to assist you in this section! Know the components of the monomer which makes up peptidoglycan (Know what G and M stand for, that they are sugars, which sugar the amino acids are connected to directly) Know what kind of linkage connects “G” and “M”; what do 1 and 4 stand for? How are the amino acids connected when they crosslink? (Hint: 3 to 4) What is a pentaglycine bridge? Note: Glycine is an amino acid, too. Is it found in Gram positive or Gram negative membranes? What amino acids are a part of the peptidoglycan monomer in Gram positive and Gram negative membranes? What’s so special about DAPA and Lysine? (Hint: They include an extra NH2 group for peptide bonding) Not every set of amino acids involve themselves in crosslinking. Are there more amino acid crosslinks in Gram positive or Gram negative? What’s the difference between an Alpha-D-Glucose and a Beta-D-Glucose? Answer: The hydroxyl (OH) group on which carbon…. How do you count carbons on a sugar? What’s the difference between B-D-Glucose and B-D- Galactose? Answer: The hydroxyl group on which carbon…. Recognize Alpha and Beta-D-Glucose and Galactose in the Chair Conformation. Glucose and Galactose are MONOsaccharides which link to form which DIsaccharide? What kind of linkage connects them? Is it the same as the one between the “G” and “M” of peptidoglycan? What enzyme tears the linkage between glucose and galactose apart? A peptide bond connects amino acids together. What does a peptide bond look like? Could you recognize one if you saw it? Where might you find a peptide bond in peptidoglycan? (Between the amino acids connected to “M”… right?)
