Life has evolved over billions of years, adapting to the changing environment. Similarly, enzymes—proteins that speed up ...

Each enzyme molecule has a special place called the active site where another molecule, called the substrate, fits. The substrate goes through a chemical reaction and changes into a new molecule ...

Enzymes originally evolved in high-temperature environments and later adapted to lower temperatures as Earth cooled.

leading to an increase in enzyme activity. This means the active site loses its important shape and can no longer form enzyme-substrate complexes, leading to a decrease in enzyme activity.

Since enzymes are quite efficient biocatalysts active under mild conditions, they are expected to be applied to varieties of environmentally benign chemical processes realized in the next generation.

Enzymes have active sites which only match specific substrates. The diagram shows how this works. In this example, the enzyme splits one molecule into two smaller ones, but other enzymes join ...

Enzymes are molecular machines that carry out the chemical reactions that sustain all life, an ability that has captured the attention of scientists like me. Consider muscle movement.
