Biology 1101 Ch. 3 Review Questions 1. An organic compound is defined as containing the element carbon and at least one hydrogen element. Covalent bonds predominate in the backbone of an organic compound. 2. A hydrocarbon is an organic compound that has only one hydrogen bonded to a carbon backbone. A functional group is when particular atoms or clusters of atoms covalently bonded to carbon. 3. The molecules of life are hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl.

Unformatted text preview: groups. 4. A condensation reaction is the covalent bonding of two molecules into a larger one; water often forms as a by-product. Hydrolysis is a cleavage reaction that breaks covalent bonds and splits a molecule into two or more parts. 5. In glucose, the chains stretch out side-by-side and hydrogen bond to one another into a tightly bundled pattern that resists being digested. 6. Triglycerides include all of the other items listed. 7. Hemoglobin has two alpha and two beta chains. The beta chains are changed by a mutation, which puts a sticky, water-repelling patch on the beta chains....
