Below is a diagram of the cell wall of a Gram-negative bacteria. Blank #1: What type of molecule is A? Be specific (for example: glycerophospholipid) Blank #2: What is the effect of molecules like A in our bodies? Blank #3: What type of molecule is B? Be specific (for example: glycerophospholipid) Gram-negative bacteria are particularly difficult to treat because their cells are shielded by a double-membrane envelope, which constitutes a formidable barrier to antibiotics. In class we discussed both lysozymes and penicillin as antibiotics that are ineffective against Gram-negative bacteria. Use blanks 4 and 5 to give a detailed explanation of how each of these antibiotics act to kill Gram-positive bacteria, and why that is not possible in Gram-negative bacteria. Blank #4: Lysozyme Blank #5: Penicillin
