Unit 2 Lecture Study Guide

1) What are the parts of an atom? Where are the subatomic particles found?

Protons, neutrons, and electrons

Protons and neutrons are located in the center of an atom in the nucleus and the electrons are located around the nucleus.

2) How does the Atomic Mass # differ from the Atomic #?

The atomic mass number is the sum of the number of protons and neutrons in the nucleus of an element and the atomic number is the number of protons that it has.

3) What is an isotope? Give an example (show how it is an isotope).

An isotope is when two or more of the same element contains equal number of protons but different numbers of neutrons in the nuclei. The element form of carbon is Carbon12 and the isotope of Carbon is Carbon14.

4) Compare and contrast the 3 basic types of chemical bonds and give an example of each.

The three basic types of chemical bonds are Ionic, Covalent, and Hydrogen. Ionic bonds are between a metal and nonmetal, covalent bonds are between two nonmetals, and hydrogen bonds are forces of attraction between atoms.

5) Why is pH important in Anatomy?

It is important because the body must be at the correct pH to function well and if it isn’t right then the body won’t function correctly.

9) Name the 4 main Organic Molecules in Biochemistry. Describe each one, and provide an example. What are the “building blocks” of each molecule? For example, protein = Amino Acid.

Proteins- monomers are amino acids and proteins and are used for various reasons in the cell such as structure, defense, and modification.

Carbohydrates- monomers are monosaccarides and can be used for storage or energy

Nucleic Acids- RNA and DNA the monomers of both of them are nucleotides and nucleic acids are used to transfer their genetic information which codes for proteins.

Lipids- glycerides, phospholipids, and...
