I would say A- Allosteric Regulation, Competitive Inhibition, and Enzyme-Substrate Complex
Allosteric Regulation- the regulation of an enzyme by binding an effector molecule at a site other than the enzyme's active site
Competitive Inhibition- a molecule similar to the substrate but unable to be acted on by the enzyme competes with the substrate for the active site
Enzyme-substrate complex- a temporary molecule formed when an enzyme comes into perfect contact with its substrate... when the substrate enters the active site.
(I’m so sorry if that’s wrong)
