Inquiry and Analysis
Do Enzymes Physically Attach to
Their Substrates?
When scientists first began to examine the chemical activities of
organisms, no one knew that biochemical reactions were catalyzed
by enzymes. The first enzyme was discovered in 1833 by French
chemist Anselme Payen. He was studying how beer is made from
barley: First, barley is pressed and gently heated so its starches
break down into simple two-sugar units; then yeasts convert these
units into ethanol. Payen found that the initial breakdown requires
a chemical factor that is not alive and that does not seem to be
used up during the process-a catalyst. He called this first enzyme
diastase (we call it amylase today).
Did this catalyst operate at a distance, increasing the
reaction rate all around it, much as raising the temperature
of nearby molecules might do? Or did it use physical contact,
actually attaching to the molecules whose reaction it catalyzed
(its "substrate")?
The answer was discovered in 1903 by French…
