Cefalexin was developed through medical biotechnology. It kills disease-causing organisms by preventing them from developing a cell wall. Which term best describes cefalexin??
A. Weakened virus
B. Bacteria
C. Antibiotic
D. Vaccine
C. Antibiotic
The term that best describes cefalexin is C. Antibiotic.
Now, let me explain how to arrive at this answer. Cefalexin is a medication that falls under the category of antibiotics. Antibiotics are substances that are used to treat bacterial infections by either killing the bacteria or inhibiting their growth.
Cefalexin specifically belongs to a class of antibiotics called cephalosporins. These antibiotics work by targeting the cell walls of bacteria. They inhibit the synthesis of the bacterial cell wall, causing the bacteria to weaken and eventually die off. By preventing the development of the cell wall, cefalexin effectively kills disease-causing organisms, specifically bacteria.
Therefore, the correct term that describes cefalexin is C. Antibiotic.
