Chemistry of Life – Chapter 2 Test Review
The test consists of approximately 40 questions including multiple choice, completion, short answer,
problem and essay. In addition, you will need to know all of the vocabulary from the chapter. You need
to know:
-
Atoms are the smallest basic unit of matter
Difference between atoms and elements
Difference and charge of protons, neutrons, and electrons
Covalent and ionic bonding
Properties of water
Hydrogen bonding in water molecules
Difference between an element, compound, and molecule
pH – definition, scale, acid/base(alkaline)
solutions
carbon chemistry/bonding
organic compounds
4 categories of biological macromolecules, their function, monomers and polymers
Endothermic/exothermic chemical reactions, energy of products and reactants and
activation energy
- Enzymes, their function, importance, enzymatic reactions
The following is information on specific benchmarks that will be assessed on this test and on the End-ofCourse exam:
SC.912.L.18.1 Describe the basic molecular structures and primary functions of the four major categories of
biological macromolecules.
SC.912.L.18.11 Explain the role of enzymes as catalysts that lower the activation energy of biochemical reactions.
Identify factors, such as pH and temperature, and their effect on enzyme activity.
Students will identify and/or describe the basic molecular structure of carbohydrates, lipids,
proteins, and/or nucleic acids.
Students will describe the primary functions of carbohydrates, lipids, proteins, and/or nucleic
acids in organisms.
Students will explain how enzymes speed up the rate of a biochemical reaction by lowering the
reaction’s activation energy.
Students will identify and/or describe the effect of environmental factors on enzyme activity.
Items referring to the factors that affect enzyme activity are limited to concentration, pH, and
temperature.
SC.912.L.18.12 Discuss the special properties of water that contribute to Earth’s suitability as an
environment for life: cohesive behavior, ability to moderate temperature, expansion upon freezing, and
versatility as a solvent.
-
Students will explain the properties of water at a conceptual level.
Students will explain how the properties make water essential for life on Earth.
Items referring to the properties of water are limited to hydrogen bonding, polarity,
cohesive behavior, ability to moderate temperature, expansion upon freezing, and
versatility as a solvent. Items may address adhesion but will not assess adhesion.
