_ reduce the enzymes productivity by blocking the sun entering into the active site due to similar shapes:

Correct answer: A. Competitive inhibitors

  • A. Competitive inhibitors
  • B. Non-competitive inhibitors
  • C. Co-enzymes
  • D. Activators

Explanation

Enzymes' productivity is reduced by blocking the active site due to similar shapes, is associated with "competitive inhibitors." Competitive inhibitors are molecules that closely resemble the substrate and compete with it for binding to the enzyme's active site. When they bind to the active site, they prevent the substrate from binding and, as a result, reduce enzyme activity

About Enzyme Inhibitors

Enzyme inhibitors reduce reaction rate by interfering with enzyme-substrate interaction or catalytic activity. Coverage includes reversible competitive, non-competitive and uncompetitive inhibition, the effects of inhibitor concentration on reaction rate, and why competitive inhibition can be reduced by increasing substrate concentration.
