Question

Chemical mechanisms that can turn off or reduce an enzyme are _____. inhibitors activators centrioles vacuoles

Answer 1

The best fit here that logically describes turning something off or reducing the activity of a system would be option A which is "inhibitors".

Answer 2

Answer;

-Inhibitors

Chemical mechanisms that can turn off or reduce an enzyme are inhibitors.

Explanation;

-Enzyme inhibitors are molecules or compounds that bind to enzymes and result in a decrease in their activity. They can bind to an enzyme and stop a substrate from entering the enzyme's active site and/or prevent the enzyme from catalyzing a chemical reaction.

-Enzyme inhibitors are classified as either competitive or non-competitive inhibitors. Competitive inhibition occurs when the substrate and a substance resembling the substrate are both added to the enzyme.

-Non-competitive inhibitors are considered to be substances which when added to the enzyme alter the enzyme in a way that it cannot accept the substrate.
