Usually, a(n) inhibitor forms a covalent bond with an amino acid side group within the active site, which prevents the substrate from entering the active site or prevents catalytic activity.

Enzyme Inhibitor

Explanation:

a(n) irreversible is right answerAn irreversible inhibitor will bind to a chemical with the enzymes that no other catalyst complexes can formIt will tie to the catalyst utilizing a covalent bond at the dynamic site which along these lines makes the chemical denaturedA case of an irreversible inhibitor is diisopropyl fluorophosphate which is available in nerve gas  There are three sorts of reversible protein inhibitors competitive inhibitors, uncompetitive inhibitors, and noncompetitive inhibitors

Characteristic expected of mineral from lava at earth's surface

phaneritic textures in which phaner means visible so phaneritic textures are standard of impertinent volcanic rocks. these rocks crystallized gradually under the surface of earth. when the magma cools deliberately then the ores have chance to develop and produce long crystals.
