1. Continue with note -taking
A) with Glycolysis
B) Kreb’s Citric Acid Cycle –
C) Electron Transport System, Oxidative Phosphorylation
Complete oxidation formula: when you combine all 3 parts of cellular combustion
Complete Cellular Respiration Formula:
C6H12O6 (s) + 6O2 —–> 6CO2(g) + 6H2O (l)
glucose –> Electron Carriers (NAD+, FAD) –> Electron transport System (Oxygen bonds with H+ to make H2O)
High Energy oxidize glucose high energy electrons used to pump H+ ions against gradient
Electrons these H+ rush out of membrane giving atp synthase energy
High energy electrons —–> Low Energy electrons
e – get oxidized oxygen gets reduced
from glucose accepting the low energy e-
C : H H :O
Electrons held loosely ———> Electrons held tightly
NAD+
FAD
Proton motor force from 4 page notes—–> Electron Transport Chain Animation above
How does the high energy electrons Pump H+ into the inter membrane space of the Mitichondrion?
Glucose ———-> Cellular Respiration ———-> O2
high energy electrons low energy electrons
REDOX Reactions – Gaining and losing or electrons-
1. REDOX : Who is getting oxidized and and reduced: Slide 9 – 17 in Cell Respiration presentation
NAD+ + H+ + 2e– —-> NADH
FAD + 2e– + 2H+ —> FADH2

Overall Spontaneous ∆G = – |
Spontaneous because of coupling Energy from electrons oxidized from glucose create the proton motor force that produces the ATP ∆G = + |
Chemical oxidation: Losing electrons (LEO) LEO the Lion says GER!!!

Period 7:
1. Review of Last Nights form.
2. Vitamin Lesson –
Yesterday we learned that the energy that we harness from glucose (from the food we eat) is due to high energy electrons that exist in C – H bonds. These electrons are shared equally because the Carbon and the Hydrogen have almost the same attraction for electrons which allows electrons to have the most freedom. Electrons with the most freedom have the greatest potential energy. When they are held closer to one or another atom the electrons “feel” the nucleus more thus have less potential energy.
The “slow” burn of glucose occurs as we take the high energy of the C-H electrons and convert them into lower energy electrons. This is accomplished by slowly taking these electrons away from the glucose in each stage of cellular respiration ( Glycolysis, Pyruvate oxidation, Citric Acid Cycle, Oxidative Phosphorylation) and combining with the final electron acceptor, oxygen and water is made. In water the electrons are held more tightly or are pulled more to the oxygen (who loves to grab electrons) These electrons are held closer to one of the atoms in a bond and have less freedom leading to a release of energy which is used to make ATP.
Do not forget there is whole host of enzymes that catalyze the many steps needed to slowly grab the high energy electrons. There are also co-enzymes (vitamins!) that help carry these electrons into electron transport system. They include NADH (Vitamin – Niacin), FAD (Vitamin – Vitamin B2 – riboflavin).
Do some vitamins give us energy? No but they help get the free energy!!! to create 34 ATP

Study:
1: Vocabulary words that match the definitions below:
Vocabulary definitions on Energy Test tomorrow – You will need to figure out the vocab words
These are the actual answers. No need to figure what the vocabulary words are.
A -Vitamins
B –uses the proton motor force to generate ATP
C – Metal ions
D –The gain of electrons
E – the protein complex that generates ATP in the Electron Transport System
F – blocks substrates from entering active sites
G – release energy when breaking down complex molecules to simpler molecules
H -a measure of randomness or disorder molecular particles or energy
I – The loss of electrons
J – the change of the shape of the active site of an enzyme when a substrate encounters it
K– Energy that can be used to do work
L– the complete breakdown of glucose to carbon dioxide

Endosymbiosis ——> mitochondria , chloroplast

[thylakoid disk——-> stack of thylakoid disks——-> granum] = light dependent reactions
[stroma —–> outside the thylakoid] = light independent reaction 0r Dark Reactions
“we are just using them for their hydrogen..haha…we take the hydrogen off them and chuck the oxygens away.”
12 H2O —–> 24 H+ (hydrogen ions/protons) + 24 NADP+ ——-> 24 NADPH——> light dependent reaction 18 ATP produced ————————————–> light dependent reaction (no ATP leftover for anything other than the light dependent reaction

24 hydrogens ripped of water eventually become 6 H2O (12) and 1 C6H12O6 (12)
6 carbons from 6 CO2 become 1 C6H12O6 (glucose)
