In an organism, the active site of each enzyme is a different shape. It is a perfect match to the shape of the substrate molecule, or molecules. This is essential to the enzyme being able to work.

For an enzyme to function, it adopts a shape that perfectly matches the molecule it processes, much like a lock matches a key ...

Life takes shape with the motion of a single cell. In response to signals from certain proteins and enzymes, a cell can start ...

The specific structure of a protein is key to its function in the same way that the shapes of everyday objects are. For example, much like a spoon is designed to hold liquid in a way that a knife ...

Enzymes are proteins that can change shape and therefore become active or inactive. An activator molecule (green pentagon) can bind to an enzyme (light green puzzle shape) and change its overall ...

In an organism, the active site of each enzyme is a different shape. It is a perfect match to the shape of the substrate molecule, or molecules. This is essential for the enzyme to work.

MIT scientists have discovered a way to control the movements of starfish cells using light, which could have biomedical applications.

For an enzyme to function, it adopts a shape that perfectly matches the molecule it processes, much like a lock matches a key. The unique grooves in the enzyme – the lock – that interact with ...
