Question

Statement best describes how antibiotics affect cellular homeostasis?

antibiotics remove chloroplast from plant cells to cause starvation
antibiotics increase the rate of DNA replication human cells by forming nucleotides
antibiotics and interfere with transport of intracellular and extracellular materials
antibiotics decrease the rate of cellular respiration in animal cells by producing oxygen ​

Answer 1

The answer is antibiotics interfere with transport of intracellular and extracellular materials.

Step-by-step explanation:

• Antibiotics are chemical therapeutic agents that either kill or hinder bacteria.
• In the bacterial cells, transport of intracellular and extracellular materials takes place through the cell wall and cell membrane.
• A special class of antibiotics, beta-lactams, inhibit the synthesis of the cell wall by inhibiting the transpeptidation reaction responsible for the synthesis of peptidoglycan, a crucial component of bacterial cell wall.

Eliminating Other Options:

• Antibiotics do not act upon plant cells and they cannot remove chloroplasts from them.
• Antibiotics can only perform bacteriocidal (bacteria killing) or bacteriostatic (bacteria growth inhibiting) functions on bacteria only.
• Antibiotics don't produce oxygen nor do they decrease cellular respiration.
