Questions & Step-by-Step Solutions

What is the primary mechanism of action of penicillins?
  • Step 1: Understand that penicillins are a type of antibiotic used to fight bacterial infections.
  • Step 2: Know that bacteria have a protective outer layer called the cell wall.
  • Step 3: Learn that penicillins target this cell wall and prevent it from being built properly.
  • Step 4: Realize that without a strong cell wall, bacteria cannot survive.
  • Step 5: Understand that when the cell wall is weakened, the bacteria can burst open (this is called lysis), leading to their death.
