with what is occuring

see explanation

Explanation:

A. substrate

B. Active site

C. Enzyme binds with substrate

D. Active site of enzyme

E. Products leaving active site

Simplified enzymatic reaction. The substrate reversibly binds to the active site of the enzyme, forming the enzyme-substrate (ES) complex. The bound substrate is converted to product by catalytic groups in the active site, forming the enzyme-product complex (EP). The bound products are released, returning the enzyme to its unbound form, ready to catalyze another round of converting substrate to product.
