1. Take out your
homework

2. Things to Know Costumes must be school appropriate
Boo Grams – sold by front office during lunches
Broadway Showcase – Nov 2-4, 6 PM in auditorium
Talent Show Sign Ups NOW!!! Auditions on Nov 7th
March on the Ridge tomorrow. Our band performs about 5:30 PM
Football at Sahuaro, Swim at CDO

3. 6O2 + C6H12O6 -> 6CO2 + 6H2O + energy
Oxygen + glucose -> carbon dioxide + water + energy

4. ATP
Adenosine TriPhosphate

5. ATP
NAD+/H
Coenzyme A (CoA)

6. How is THIS ‘energy’?

7. Oxygen and Electrons ReDox reactions Oxidation – Reduction reactions
When NAD+ gets converted to NADH…
What happens to its ‘charge’?
It goes down = it gets REDUCED
Gaining electrons = reduction
Losing electrons = oxidation

8. Oxygen and Electrons OIL RIG Oxidation Is Loss, Reduction Is Gain
It’s really important in your body
This is really what kills you in the end (and water and cell division)

9. Oxygen and Electrons

10. Kreb’s Cycle (Citric Acid Cycle)
Regulated by many different enzymes!
Follow along

11. Kreb’s Cycle (Citric Acid Cycle)
Regulated by many different enzymes
Occurs in mitochondrial matrix
Why 2 membranes?

12. Kreb’s Cycle (Citric Acid Cycle)
Regulated by many different enzymes
Occurs in mitochondrial matrix
A two-carbon compound attached to a co- enzyme enters
The carrier/co-enzyme is Coenzyme A
Basically a nucleotide with vitamin B5 attached
CoA

13. Kreb’s Cycle (Citric Acid Cycle)
The Kreb’s Cycle needs the two-carbon compound
The coenzyme isn’t a reactant, it’s a carrier
Since it’s a cycle, it ‘begins’ and ‘ends’ at the same spot

14. Kreb’s Cycle (Citric Acid Cycle)

16. How do you go from NAD+ to NADH?
And FAD to FADH2?
Vitamin B12!

17. Just ONE ATP molecule. Not enough to live on

18. Kreb’s Cycle (Citric Acid Cycle)
Remember, this…
Happens here

19. Kreb’s Cycle (Citric Acid Cycle)
NAD+
Nicotinomide Adenine Dinucleotide

20. NAD+ vs NADH

21. NAD+ vs NADH

22. NAD+
This is the vitamin Niacin
Vitamin B3

23. Kreb’s Cycle (Citric Acid Cycle)
Reduces NAD+ and FAD to NADH and FADH2
Produces CO2 as a by-product

24. NOW
READ and note pages
Written answer to Obj. 9

25. Where does the oxygen come from?
The “glucose”
What happens to the carbon dioxide?
The water?
What ‘energy’?
