Which of the following organic compounds is known to target the bacterial cytoplasmic membrane?
A
Sulfonamides
B
Polymyxins
C
Tetracyclines
D
Penicillins
Verified step by step guidance1
Understand the function of each compound: Sulfonamides inhibit folic acid synthesis, Tetracyclines inhibit protein synthesis, Penicillins inhibit cell wall synthesis, and Polymyxins target the bacterial cytoplasmic membrane.
Recognize that the bacterial cytoplasmic membrane is a critical structure that maintains the integrity and functionality of the cell.
Identify that Polymyxins are a class of antibiotics that interact with the phospholipids in the bacterial cytoplasmic membrane, disrupting its structure and function.
Recall that Polymyxins are often used against Gram-negative bacteria due to their ability to penetrate the outer membrane and target the cytoplasmic membrane.
Conclude that among the given options, Polymyxins are the compounds known to target the bacterial cytoplasmic membrane.
