Which type of bacteria can be killed by oxygen radicals and why?
a. Anaerobic bacteria - because they lack the enymes needed to neutralie oxygen radicals, making them vulnerable to their damaging effects.
b. Gram-positive bacteria - because their thick cell wall is less effective at protecting them from oxygen radicals.
c. Gram-negative bacteria - because they have a thinner cell wall and are more susceptible to damage from oxygen radicals.
d. Facultative anaerobic bacteria - because they can switch between aerobic and anaerobic metabolism, making them susceptible to oxygen radicals during aerobic conditions.
