Final answer:
Fluconazole is very effective against certain types of fungi, particularly Candida species. It disrupts fungal cell membranes by inhibiting ergosterol biosynthesis.
Step-by-step explanation:
Fluconazole is very effective against certain types of fungi, particularly Candida species. It inhibits the synthesis of ergosterol, a crucial component of fungal cell membranes, thus disrupting their structure and function. By targeting ergosterol biosynthesis, fluconazole exhibits selective toxicity against fungi while having fewer side effects on human cells. It is commonly used to treat various fungal infections, including oral thrush, vaginal candidiasis, and systemic yeast infections.
