Cell Respiration

Take notes on the following videos describing cell respiration and write the notes in your handouts.  Summarize the fate of the Hydrogens delivered by NAD+  and FAD+    In particular pay attention to what happens in the inner membrane of the mitochondria.  There will be an open-note quiz on cell respiration next period:






Answer these questions on the third video while you watch.
1.  What is the purpose of Cellular Respiration?
2.   What is ATP and ADP made of?
3.    What are the three steps of Cellular respiration?
4. In glycolysis, we must make ATP by spending some ATP.  Explain
5.   How many NADH is made in Glycolysis?
6.  In the absence of Oxygen, what pathway does glycolysis take?
7.  When yeast do fermentation, what do they make as a byproduct?
8.  When muscles do fermentation what do they make?
9.  At the end of glycolysis,  pyruvate grabs oxygen,  releases CO2 and what 2 carbon molecule is formed?
10  Acetyl Co A enters the Kreb's citric acid cycle where it releases more CO2 and more NADH and FADH2 are produced.  What is the role of NAD+ and FAD+?

11.  The electron transport chain is the "real money maker" for making ATP.  How many ATP can be made by the electron transport chain?

12.  Look at your diagram and  name all the enzymes imbedded in the inner membrane of the electron transport chain

13.  Which enzyme makes ATP?
14.  What did you eat for breakfast?
15.  Put your name on these questions and hand them in!

Next, look in your textbook on Cell respiration

MEIOSIS and MITOSIS

Vulcan Mating Ritual

Mating Lab: 

Purpose:  To have hypothetical offspring with at least 4 other individuals

In the class and calculate the probability of certain traits using a punnet

Square.  Next, you will perform a Vulcan mating ritual (pon farr) where

you randomly pick an allele from the other person and they randomly pick

one of your alleles.  Then observe the traits of your offspring.  Have 8 kids per mate

Keep track of the genotype of each kid.  By the end of the activity, you will have 32 kids

Method:

Write down your phenotype for the following characteristics:

Earlobe attachment or unattached

Tongue rolling or not                       T       t

Cleft chin or smooth chin.                C     c

Widow’s peak or not                          W  w

Natural curl or straight hair         N  n

Dimples or not       D    d

Righty or Lefty       R   r

Freckles or not       F  f

Girl XX or boy XY

For each trait, make the genotype as alleles on two small pieces of paper.

 Write your phenotypes now:

For each mate you have draw nine punnet squares  representing

 each trait and

calculate the Probability of each trait.

Homologous Chromosomes, Genetics and Mitosis vs Meiosis

You will review some notes on homologous chromosomes and also go over some basic Genetics concepts.  Further you will review the main concepts of Mitosis vs Meiosis as you review this video

DNA Lesson

We will explore the nature of DNA. We will review these notes here  and you will get a worksheet looking at DNA replication.

Neuroscience symposium

If you were not able to go to the Don Rix lecture, here is another opportunity
