Return to CHAPTER 20. Control activities are the policies, procedures, techniques, and mechanisms that help ensure that management's response to reduce risks identified during the risk assessment process is carried out. In other words, control activities are actions taken to minimize risk.
Cells regulate enzyme activity through two methods: allosteric inhibition and competitive inhibition. Allosteric inhibition is when something (an ion, an organic chemical, etc â¦.) bonds to a site on the enzyme (not on the active site), and changes the shape of the enzyme. Competitive inhibition is when something (an ion, an organic chemical, etc.) enters the active site so that the true substrate cannot enter into the enzyme to have a reaction.
