which of the following characteristics is not associated with allosteric regulation of an enzymes activity?
a mimic of the substrate competes for the active site.
regulatory molecules bind to a site remote from the active site.
inhibitors and activators may compete with one another.
the enzyme usually has a quaternary structure.

Explanation:

• Allosteric regulation involves regulatory molecules binding to a site other than the active site (not competing for the active site like a substrate mimic). Allosteric enzymes often have quaternary structure. Inhibitors and activators can compete in allosteric regulation.

Answer:

A. A mimic of the substrate competes for the active site.
