Cephalosporins function primarily by inhibiting cell wall synthesis in bacteria. They are a class of β-lactam antibiotics that are structurally and functionally similar to penicillins. By interfering with the synthesis of the bacterial cell wall, cephalosporins weaken it, leading to cell lysis and ultimately bacterial death. This mechanism is particularly effective against a wide range of bacteria, making cephalosporins valuable in treating various infections.

The other options do not align with the primary function of cephalosporins. Reducing fever is typically a function of antipyretics, while enhancing metabolic rates is more related to substances like stimulants or certain hormones. Stimulating insulin release correlates with specific medications used in diabetes management, which is unrelated to the action of cephalosporins. Thus, the correct answer underscores the primary antibacterial action of cephalosporins related to cell wall inhibition.
