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 ...

This illustration depicts the process of enzyme catalysis. The enzyme (blue) binds to its substrate (red) to form an enzyme-substrate complex. The enzyme then catalyzes the conversion of the substrate ...

The transformation of healthy cells into invasive colorectal tumors is an extraordinarily complex process involving numerous ...

Enzymes are highly specific to their substrates. They bind these substrates at complementary areas on their surfaces, providing a snug fit that many scientists compare to a lock and key.

Enzymes, the core catalysts in life, drive critical biological processes ranging from metabolic regulation to energy ...

Scientists are exploring a bacteria that consumes methane to produce biodegradable plastics. Called Methylocystis ...

About 98% of lignin created as a forestry by-product from plants is discarded, but a new enzyme could be the key to ...

Enzyme mechanisms are the chemical transformations, and the steps within them, generated by enzymatic action on substrates. The mechanism of enzyme catalysis is similar in principle to other types ...

A continued increase in pH results in a sharp decrease in activity as the enzyme’s active site changes shape. It is now denatured. As the substrate concentration increases so does the rate of ...
