Question

question
how do enzyme inhibitors work?
answer
they bind to an enzyme, which alters the active site so a substrate cannot bind.
they change the charge on the substrate so that it can no longer bind to the enzymes active site.
they bind to the substrate, which blocks the enzyme from binding.
they bind to the substrate, changing its shape so it cannot bind to an enzyme.
i dont know yet

Explanation:

Enzyme inhibitors can be competitive or non - competitive. Competitive inhibitors bind to the active site of an enzyme, while non - competitive inhibitors bind to an allosteric site, altering the active site's shape so a substrate cannot bind. The first option correctly describes non - competitive inhibition. Other options are incorrect as inhibitors don't change the charge on the substrate directly, and they don't bind to the substrate in the way described in the other false options.

Answer:

They bind to an enzyme, which alters the active site so a substrate cannot bind.
