When we have a bacterial infection, we often take antibiotics. Why do antibiotics only kill bacterial cells and not our own human cells? They do kill human cells but there are far more human cells than bacterial cells and they will quickly repopulate after the infection. Antibiotics are proteins that can only bind to bacterial cell wall receptors. Antibiotics target structures of bacterial cells that human don't have, such as a nucleus. Antibiotics target structures of bacterial cells that human don't have, such as peptidoglycan.

Which of the following options best describes the process of selection for antibiotic-resistant bacteria in the presence of an antibiotic? Antibiotic resistance occurs when the human body resists an antibiotic; the bacteria are not under selective pressure Antibiotic-resistant cells are naturally stronger, so they always take over in the presence of antibiotic- sensitive cells Antibiotics kill off sensitive cells, while resistant bacteria survive and multiply O In the presence of antibiotics, most bacterial cells react by becoming resistant before they start dividing again MacBook Air DD 000 80 F9 000 F8 F7 F5 F6 F3 F4
How does having a capsule increase the virulence of a bacteria cell? A capsule gives bacteria antibiotic resistance. Bacteria with a capsule cannot be phagocytized by immune cells. The capsule speeds up asexual reproduction of the bacteria. The capsule increases bacteria motility.

How effective are antibiotics against viral infections? Antibiotics can prevent viral entry into the cell by binding to host-receptor proteins. Antibiotics work by inhibiting enzymes specific to bacteria. Antibiotics have no effect on eukaryotic or virally encoded enzymes. Antibiotics activate the immune system, and this decreases the severity of the infection. Antibiotics do not kill viruses because viruses do not have DNA or RNA.
