In an Electrophilic Aromatic Substitution (EAS) reaction, the benzene ring acts as a nucleophile that attacks an electrophile. The reaction mechanism below outlines the flow of electrons that occurs during all EAS reactions. Here are the six EAS line reactions you should know for the DAT:

Digestive Enzymes – An Overview

Digestive enzymes is a topic frequently tested on the Biology section of the DAT. Knowing the function of key enzymes, where they are produced, and how they are regulated will translate to easy points come test day. Below, I’ve outlined how food is broken down from the moment of ingestion until it is absorbed in Read More
