Chapter 4, Problem 1SL

Review Burning Question 4.4, which explains how alcohol-based hand sanitizers disrupt the functions of enzymes and other biochemicals in living cells. Instead of alcohol, some hand sanitizers contain chemicals that kill germs by targeting specific structures inside bacterial cells. Why might these ingredients select for resistant bacteria, while alcohol-based ones do not? What factors might determine whether a person uses hand sanitizer rather than washing hands with soap and water (which wash away bacteria instead of killing them)? If you buy a hand sanitizer, what information should you look for before deciding which product to select?
