Enzymology is the study of enzymes and enzyme-catalyzed reactions. Enzymes are biological catalysts that accelerate the rate of biological reactions. They can also perform multiple reactions ...

Enzymes originally evolved in high-temperature environments and later adapted to lower temperatures as Earth cooled. Scientists discovered that a key shift in enzyme function occurred over ...

Enzymes evolved to efficiently operate in low-temperature environments via key substitutions of amino acids in their active site, which lowers the activation energy of catalytic reactions. Life has ...
