BSC 2085
CHEMISTRY OBJECTIVES
Be able to apply the following terms.

• Define atom, elements and molecule.List the major elements that form the bulk of body matter.
• List the subatomic particles; describe their relative masses, charges, and positions in the atom.
• Understand the role of electrons in bond formation.
• Differentiate between ionic, hydrogen and covalent bonds in formation as well as role in the body. Know examples of molecules where these bonds are found.
• Compare and contrast polar and nonpolar covalently bonded compounds concerning solubility, specifically in terms of whether the molecule can diffuse through the oil molecule-based cell membrane.
• Explain the role of water, solutes and dissolved substances, particularly ions, in solutions. Define osmotic pressure and describe the conditions that would raise osmotic pressure.
• Define acid and base, be able to read pH scale and determine level of H ion concentration.
• Explain the role of dehydration synthesis and hydrolysis reactions in the formation and breakdown of organic molecules. Relate the role of water and energy in each type of reaction.
• Relate the roles of water, in general..
• Compare the structures and functions of the four major organic molecule classifications (carbohydrates, proteins, lipids and nucleic acids). Identify the building block molecules for each of the above classifications.
• Describes the general mechanism of enzyme activity. Understand the role of temperature and pH in enzyme structure and function. Describe factors that affect chemical reaction rates.
• Explain the role of ATP in cell metabolism.
