Solved by a verified expert:1. People also have 70S ribosomes in the mitochondria found in nearly every cell. Why do antibiotics that interfere with ribosome function (and thus protein synthesis) kill bacteria but not the patient? 2. Some antimicrobial agents imbed in membranes producing unregulated channels between the cell and its environment. Based on your understanding of semipermeable membranes, how could a chemical like this cause the death of the bacterial cell?
