IPA: /nɒnˈɛnzaɪmɪk/
KK: /nɑnˈɛnzaɪmɪk/
Not related to or involving enzymes.
The reaction was nonenzymic, meaning it did not require any enzymes to occur.
Nonenzymic → It is formed from "non-" (meaning not) and "enzymic" (from the Greek "enzymon", meaning leaven or ferment). The word "nonenzymic" refers to processes or reactions that do not involve enzymes.
Think of 'non-' meaning not, and 'enzymic' relating to enzymes — so nonenzymic means not involving enzymes.
