Species, Cells, and Evolution

1. Use your understanding of Gibb’s free energy, endergonic reactions, and exergonic reactions to predict whether a chemical reaction occurs spontaneously or requires energy input. 2. Use rules of thumb about anabolic and catabolic reactions to predict whether a reaction is exergonic or endergonic. 3. Explain how the energy of activation slows some chemical reactions, and how this barrier can be overcome by an enzyme. 4. Explain the roles of dehydration and hydrolysis reactions in the formation and breakdown of polymer macromolecules using monomers. 5. Analyze whether a macromolecule monomer is a monosaccharide, an amino acid, or a nucleotide.
