This 51-slide teaching PowerPoint presentation covers 4.A.1 (Biomolecules) in the AP Biology (2015) curriculum. Each slide includes the 'Essential Knowledge' being covered as well as key terms that students should make note of (editable).
The topic has been divided into 6 smaller sections:
• 1 - Molecular Biology
• 2 - Nucleic Acids
• 3 - Proteins
• 4 - Lipids
• 5 - Carbohydrates
• 6 - Directionality
The presentations themselves contains minimal information as they are intended to be used with teacher guidance. There are 'Video' slides throughout which link to relevant and informative YouTube content. The slides are formatted to be visually pleasing and to also print well for handouts or revision. Please see the preview file (first 8 slides) for an idea of the aesthetic and level of detail in the presentation. The relevant 'Essential Knowledge' can be found below.
I have had success using these presentations to review topics after students have been exposed to the material at home. I typically have the class read relevant material (book, site, etc.) and then watch the videos the day before introducing a topic. During the class period, I use the slides to structure the discussion around the AP Bio Essential Knowledge objectives. The remaining class time is spent reinforcing the knowledge or working on activities geared toward the 'Learning Objectives'.
**These presentations are based on the AP Biology Course Guide and does not follow any textbook
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!

The Essential Knowledge covered includes:
4.A.1 - Biomolecules
The subcomponents of biological molecules and their sequence determine the properties of that molecule.
a. Structure and function of polymers are derived from the way their monomers are assembled.
- 1. In nucleic acids, biological information is encoded in sequences of nucleotide monomers. Each nucleotide has
structural components: a five-carbon sugar (deoxyribose or ribose), a phosphate and a
nitrogen base (adenine, thymine, guanine, cytosine or uracil). DNA and RNA differ in function and differ
slightly in structure, and these structural differences account for the differing functions.
- 2. In proteins, the specic order of amino acids in a polypeptide (primary structure) interacts with the environment
to determine the overall shape of the protein, which also involves secondary tertiary and quaternary
structure and, thus, its function. The R group of an amino acid can be categorized by chemical properties
(hydrophobic, hydrophilic and ionic), and the interactions of these R groups determine structure
and function of that region of the protein.
- 3. In general, lipids are nonpolar; however, phospholipids exhibit structural properties, with polar regions that
interact with other polar molecules such as water, and with nonpolar regions where dierences in saturation
determine the structure and function of lipids.
- 4. Carbohydrates are composed of sugar monomers whose structures and bonding with each other by
dehydration synthesis determine the properties and functions of the molecules. Illustrative examples
include: cellulose versus starch.
b. Directionality inuences structure and function of the polymer.
- 1. Nucleic acids have ends, defined by the 3' and 5' carbons of the sugar in the nucleotide, that determine the
direction in which complementary nucleotides are added during DNA synthesis and the direction in which
transcription occurs (from 5' to 3').
- 2. Proteins have an amino end and a carboxyl end, and consist of a linear sequence of amino acids connected
by the formation of peptide bonds by dehydration synthesis between the amino and carboxyl groups of
