Verified step by step guidance

Understand the role of enzymes: Enzymes are biological catalysts that speed up chemical reactions in cells. They have specific active sites where substrates bind to form an enzyme-substrate (ES) complex.

Explore how inhibitors affect enzymes: Inhibitors are molecules that decrease enzyme activity. They can bind to the enzyme or the ES complex, preventing the enzyme from functioning normally.

Binding to the free enzyme: Some inhibitors bind directly to the enzyme before the substrate can bind, preventing the formation of the ES complex. This is known as competitive inhibition.

Binding to the ES-complex: Inhibitors can also bind to the ES complex, preventing the reaction from proceeding. This is known as uncompetitive inhibition.

Blocking or altering the active site: Inhibitors can block the active site or alter its shape, preventing substrate binding or catalysis. This can occur through non-competitive inhibition or allosteric regulation, where the inhibitor binds to a site other than the active site, causing a conformational change.
