To achieve this goal, cells organize reactions into various enzyme-powered pathways.

Metabolic pathways are integrated and controlled enzyme-catalysed reactions within a cell. In animals, specific metabolic pathways can produce vitamins and haemoglobin. Metabolic pathways can be ...

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 ...

The cell can control a metabolic pathway by the presence or absence of a particular enzyme. The cell can also regulate the rate of reaction of key enzymes. The binding of the enzyme to its ...
