AP Biology Exam Study Guide and Tips Questions and Answers Organic Compounds are molecules that contain carbon. Hydrolysis Reaction is a compound that dissolves in water and is the decomposition of something in the presence of water. Dehydration Reaction releases water. Oxidation-Reduction Reactions involve the gain (oxidation) or loss (reduction) of electrons. Anabolic Reactions create larger molecules from smaller ones. Catabolic Reaction breaks down larger mole...

AP Biology Exam Review Unit 1 Questions and Answers What is a hydrogen bond? One of the weak chemical bonds that are central to the chemistry of life; a hydrogen bond is characterized by the non-covalent attraction between a hydrogen and an electronegative atom. When a hydrogen atom is covalently bonded to an electronegative atom, the hydrogen atom has a partial positive charge that allows it to be attracted to a different electronegative atom nearby. Typically, it is attracted to nitrogen or ...
