- won't follow the lock-and-key pattern of enzyme binding

Explanation:

An enzyme is a biological catalyst that regulates the rate of chemical reactions in living systems. Enzymes are proteinous in nature and every protein is made up of an amino acid sequence. The amino acid sequence forms a three-dimensional shape that determines the functionality of the enzyme.

Enzymes catalyze reactions by binding to their substrates in a lock and key pattern. This makes enzymes substrate-specific. If the enzyme's normal shape changes, the following will occur:

- Less binding of substrate

- won't follow the lock-and-key pattern of enzyme binding.
