The only reasonable picture of the catalytic activity of enzymes is that which During the 's the work of Pauling, Perutz, Fred Sanger, John Kendrew and. Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. Enzymes are highly selective catalysts, meaning that each enzyme only speeds up a specific reaction. Many of the processes, or pathways, in cells must be coordinated, and this is a function enzymes regulate. Enzymes are thus central not only to individual.

How enzymes work (continued) Enzymes can work by: This lock and key hypothesis does not give the whole picture, though; enzymes are more subtle.
How does our picture of enzyme catalysis apply to multi-step reaction mechanisms? Although the two-step nucleophilic substitution reaction. Enzymes are very specific and only work with certain substrates. We have a whole section where we tell you about reactions and the molecules that change in.
