Quizplus · Accepted Answer

Catalase-negative cells lack the enzyme catalase, which breaks down hydrogen peroxide into water and oxygen. When incubated aerobically, these cells cannot efficiently neutralize the toxic effects of hydrogen peroxide produced during aerobic metabolism, leading to minimal or no growth depicted by line C.
