Consequence of a substance with similar spatial conformation

Question

For enzymatic reaction what is the consequence of a substance with similar spatial conformation as an enzymatic substrate? How is this kind of substance recognized?

Answer 1

Substances which “simulate” substrates can join to the activation center of enzymes therefore blocking the true substrates to join to such enzymes and paralyzing the enzymatic reaction. These “fake substrates” are termed as enzyme inhibitors. The binding of enzyme inhibitors to enzymes can be irreversible or reversible.
