BCH210 Midterm 2 & BCH210 Week 4, Completely Solved Correct Questions and Answers 100% A+ Properties of Catabolism - CORRECT ANSWER-Breaking down larger macromolecules, exergonic, oxidative. Creates high energy molecules in teh process (ex. ATP, NADH, FADH2) Properties of Anabolism - CORRECT ANSWER-Building up macromolecules from smaller molecules, reductive, endergonic. Requires high energy molecules to fuel the reaction (ex. ATP, NADH, FADH2). Metabolism - CORRECT ANSWER-The conversion of o...

1. Question: Anabolic reactions characteristics • forming large molecules from smaller molecules 2. Question: Chemical reactions that can proceed toward either anabolism or catabolism are called_ what_? • amphibolic 3. Question: Catabolic reactions characteristics • Catabolic reactions break down larger molecules, such as carbohydrates, lipids, and proteins from ingested food, into their constituent smaller parts. They also include the breakdown of ATP, which releases the energy nee...
