Verified step by step guidance

Understand the concept of antibiotic resistance: Antibiotic resistance occurs when bacteria evolve mechanisms to resist the effects of drugs that once killed them or inhibited their growth. This is a form of natural selection where the bacteria with resistance traits survive and reproduce.

Identify the role of enzyme-catalyzed reactions in antibiotic resistance: Enzymes can modify antibiotics, rendering them ineffective. Bacteria can acquire genes that encode these enzymes, leading to resistance.

Consider the mechanism of enzyme-catalyzed reactions: Enzymes act as catalysts to speed up chemical reactions without being consumed. In the context of antibiotic resistance, enzymes can alter the structure of antibiotics, preventing them from binding to their target sites in bacteria.

Compare enzyme-catalyzed reactions with other options: Nucleophilic substitution, hydrogenation, and electrophilic addition are types of chemical reactions that do not directly relate to the concept of antibiotic resistance as they do not involve the modification of antibiotics by bacterial enzymes.

Conclude that enzyme-catalyzed reactions are most closely related to antibiotic resistance: These reactions are directly involved in the biochemical processes that enable bacteria to survive in the presence of antibiotics, illustrating natural selection.
