Identify the bonds broken and formed in each step of the following reaction. In addition, draw curved arrows to represent the flow of electrons and identify the electrophile and nucleophile in each step.
Describe what happens to when Snicker bars and Twizzlers, both physically and chemically, once they pass through your lips. In other words, trace the main ingredients (from a complex food source completely through molecular and submolecular levels) from the moment you start eating them until they are completely broken down into building blocks and cellular energy. Focus your answer on what happens to the key molecules in the food, and on the cellular aspect of these conversions. Also, describe how...
