11/10 – Tuesday – “D” Day – Homework:
We left off in class going back in time discussing the origin of life, the age of the planet, and Stanley Miller’s Experiment that tested to see if life can begin from the basic compounds that the early earth had. Although he was not successful in creating life in his laboratory he was able to see that organic (life based) compounds could be made. So no life was created but molecules or compounds that support life were made!
Can you guess where we are headed?
Yes we are headed in the direction of the details that support life exactly how hereditary actual works in the atomic level. We are going to study how alleles are delivered to offspring by looking at the biochemistry and the genetics that supports evolution and the chromosomal line of inheritance.
The first day should connect to the last day!
In order to understand the microscopic details of hereditary we need to study chemistry or biochemistry.
What we will be doing is studying the basics of chemistry in order to work towards understanding
1) how amino acids make proteins
2) How different amino acids create different proteins that will function differently
3) What is DNA, RNA and their roles in coding for alleles (amino acids —> proteins)
4) How Chromosomes (DNA) actually replicates in the S1 phase of the growth cycle of a cell.
This introductory lectures are made to gain a basic understanding of the patterns that occur in nature in terms of atoms that are in proteins, amino acids, and DNA (etc).
1. Please watch the lecture below and add notes to your blank periodic table. It will be important for you to also look at a real periodic table of elements while you do this.
2. Then watch the lecture below it with Elvira.
3. Complete the Form below:
This is a classroom style lecture with me introducing Elvira the outermost electron teaching the three basic trends of the periodic table.

Period 7/8 – I will give you a partial study hall at halfway part of period 8
BioChemistry!
1. Complete slides up to amino acids.
2. Elvira the Outer most Electron/homework review.
3. Lewis dot Diagrams of organic molecules
Valence electrons/covalent bonds/stability – organic molecule
Amino acid structure – R groups, different Amino acid differ by R groups
Peptide bond basics – water leaves (dehydration synthesis) and the N and C bond maintaining proper stability. Polar molecule vs. Nonpolar molecule.
Classwork –
11/12 – Thursday “A” Day Homework:
1. Please watch the lecture (below the form) and with the Covalent ditto 1 -Electron Dot Diagrams worksheet I gave out today.
I mention R – groups from Amino Acids. these are parts of the amino acids that can be polar or non- polar.
 |
So these molecules are amino acids! They are what the DNA codes for and when you connect these amino acids you get a protein! The R groups are the part of the amino acid that is in green and these can be polar and non- polar! |
2. Complete the entire worksheet (write the Lewis dot structure) and label each molecule as either polar or non- polar.
3. Review with the key above.
4. Complete Polar vs, Nonpolar Molecules Form.
Lecture for Covalent ditto 1 -Electron Dot Diagrams worksheet:
End of Thursday..
11/12 – Friday – “B” Day –period 7B, 8B– I 7(B) 8(B,D) AP BIOLOGY – (double period Lab)
-period 7B, 8B -R 7(B) 8(B,D) AP BIOLOGY – REMOTE INSTR
The Blue team is remote today. Please move to the Remote Instruction Page.
Period 7,8 –
1. Review origin of life presentation through Amino acids
2. Amino Acid Structure – using electron dot diagrams
3. Polar vs. Non- polar molecules-
a) Polar molecular atractions – (H – bonds) – HYDROPHILIC
b) Nonpolar attractions – (LDF’s) – HYDROPHOBIC
4. Resubmit form from last night,
5. Demo –
1. – electrostatic streams of water
2. Like dissolves like – intermolecular attractions.
a) Sweat and sharpie –
b) acetone and Polystyrene
c) starch and water.
d) Demonstrated the 2 bottles with 2 types of dyes.
Class Notes:
Like dissolves Like” because the intermolecular attractions between molecules are similar.
Hydrophilic (water loving) molecules prefer to ATTRACT molecules that are also like water.
 |
Water has strong INTER molecular attractions because it is polar. The electron rich oxygen end is negative and the electron deficient end of hydrogen is positive. Water will orientate itself correctly liquid or in the solid phase so that positives (H end) attract the negatives (oxygen).
These are not Bonds!! Bonds are intramolecular forces that are determined by valence electrons filling their outermost energy level. The only molecules that can GET into water must also have positive and negative ends to dissolve in water!
|
Water is polar and thus has positive and negative (poles). Other molecules that are polar will also have positive and negative poles that water can attract to and mix into water.
polar glucose ( C6H12O6) molecule glucose dissolved in water
The diagram is illustrating the Hydrogen Bonding between the polar water and polar glucose molecules. H – Bonding, is NOT a bond but an attractive force between polar molecules that have electron deficient hydrogens.
*Notice that the oxygen end of the water molecule is Attracted to the positive end of the Hydrogen that is BONDED to an atom that that has a large attraction for electrons. The Hydrogen must be electron deficient in order for it to be positive. THAT means that is must be bonded to either F,O, or N to create this electron deficient hydrogen.
These three element pull the shared electrons (electrons in the bond) AWAY from the hydrogen ENOUGH to make the Hydrogen positive enough so that it can ATTRACT to electron rich (negative end) of another polar molecule.
The reason elements F,O, or N create electron deficient Hydrogens is because they have the greatest electronegativity (attractions for electrons). Here is a list of electronegativity values for some of the elements of the periodic table.
Hmm. Does this trend follow the atomic radii trend that we looked at last week?? YES!
Notice which elements have the greatest attraction for electrons (electronegativity). F , O, and N!
Also Notice that Hydrogen (2.20) and Carbon (2.55) have electron configurations differences less than .40 and generally any difference in electronegativity less than .40 between 2 elements in a sharing bond (covalent) is considered “equal sharing’ and thus will not create electron rich or electron deficient areas of a molecule. THIS MEANS THAT HYDROGENS THAT ARE BONDED TO CARBON ARE NOT ELECTRON DEFICIENT AND WILL NOT H-BOND!
Molecules that are not polar do not have Electron deficient Hydrogen and thus MUST attract each other by another method – LDF’s or non-polar attractions.
Today’s Demo: NON-polar dissolves non-polar!!!
11/13 – Friday – “B” Day Homework – worksheets are subject to collection for a quiz
grade next week.
1. Make another submission to Last nights form. You will have received an email with your grade from the first submission by now . The first sub does not count!
2. Please complete the Amino Acids worksheet 1718-New.pdf worksheet and follow along with me using the video below.
Video for the Amino Acid worksheet.
Please follow the order below!
2: Watch the disulphide video.
This represents the a covalent bond between R groups that have a S (sulfur). This is the final type of way that proteins (R groups) can attach to themselves and fold into their “active” shape.
3: Watch the protein folding video.
*Notice the primary structure, secondary, tertiary, and quaternary structure that proteins can have by attracting themselves by R groups attracting or bonding(cysteine – disulphide bonds) with other R groups.
* 3 ways that amino acids can attract each other:
A) polar attractions (H – bonds)
B) Nonpolar attractions (LDF’s)
C) Ionic attractions (some R groups have charges and thus a negative charge ION R group from one amino acid will attract positive charged ION R groups from another amino acids.)
(+) ION —– (-) ION is a IONIC ATTRACTION!
4: Complete the protein packet and review with the key – do your best here and I will review. I do have video (Optional video below ) that reviews parts of the packet. WATCH THIS VIDEO FIRST! SO I guess it is not optional!
Use this to name you amino acids in the above packet:
Video 1:
Video 2:
Optional video on Mr. Grodski reviewing a little bit of the packet.
