Answer:
Polyphenol oxidase (PPO) activity was determined by measuring the initial rate of quinone formation,
as indicated by an increase in the absorbance units (AUs) at 420 nm. An increase in absorbance of 0.001 min−1 was taken as one unit of enzyme activity

This measures the probability of an interaction occuring. For typical interactions between ions and electrons, or between two nuclei, these cross sections are generally measured in barns. (Science: anatomy) a transverse cut through a structure or tissue. The opposite of a cross-section is a longitudinal section.
