1/5 Overview of Respiration

3. Crash Course ATP & Cellular Respiration

4. Aim #38: How do our cells carry out aerobic cellular respiration?

5. 1) What is the formula for cellular respiration?
C6H12O6 + 6O2  6CO2 + 6H2O + 38ATP

6. 2) Let’s not forget the Big Picture:
ATP P P + +
Energy
+ ADP +
Energy
Cell Activities
Cell Respiration

7. 3) Cell Respiration Involves Oxidation-Reduction Reactions
This involves the transfer of H+ ions and electrons
from one compound to another
Every time H+ and its electrons are transferred,
energy is also transferred

8. Oxidation-Reduction Reactions

9. 4) Oxidation vs. Reduction
A process that consumes energy
2) An atom gains electrons
3) A substance gains H+
4) GER- gain electrons
reduction
Oxidation:
A process that
releases energy
An atom loses electrons
3) A substance loses H+
4)LEO- lose electrons
oxidation

11. NAD+ & FAD+ In cells, there are special compounds that help carry
Hydrogen and their electrons from one
compound to another.
**The Hydrogen and electrons are both sources of
energy.
These structures help enzymes work, so they are
known as coenzymes

12. 5) What is NAD+ and NADH?
Compounds transfer electrons and Hydrogens to NAD+ during cell respiration forming NADH.
NADH will be utilized later on in cellular respiration
to create more ATP molecules

13. Cell Respiration & Burning are types of Oxidation
ENERGY
Series of reactions
Occurs at body temp
Involves enzymes
May be aerobic or
anaerobic
Single reaction
Occurs at high temps.
No enzymes required
Aerobic- must have O2

14. 6) Structure of the Mitochondria
2 Membranes (inner
& outer)
Matrix- thick fluid on
the inside of the inner
Membrane
3) Intermembrane Space- the space between the 2 membranes.
** Many of the enzymes & other molecules are involved
in respiration are built into the inner membrane.

1/6 Glycolysis

16. The Steps of Aerobic Cellular Respiration
1. Glycolysis (same as anaerobic respiration)
2. Acetyl CoA Formation
3. Krebs Cycle
4. Electron Transport Chain (ETC)

17. 7) Stage 1: Glycolysis Where does Glycolysis take place? Cytoplasm
Glucose + 2ATP + 2NAD+  2 Pyruvate + 2NADH + 4ATP
Where does Glycolysis
take place?
Cytoplasm

18. Stage 1: Glycolysis 3 Carbon Pyruvate 3 Carbon 6 Carbon Structure
Glucose + 2ATP + 2NAD+  2 Pyruvate + 2NADH + 4ATP
3 Carbon
Pyruvate
3 Carbon
6 Carbon
Structure
** Initial investment of energy
to break Glucose (2 ATP)
Pyruvate

19. Glycolysis Summary: It takes place in the cytoplasm
It requires an input of 2 ATP molecules
It creates 4 ATP molecules (net gain of 2)
It creates two NADH molecules
5) The 2 pyruvates still hold most of the energy
of the original glucose molecule
6) It does not require oxygen!!!!!

20. 8) Stage 2: Acetyl CoA Formation
takes place in the Matrix of the mitochondria
Pyruvate created during glycolysis now diffuses into the mitochondrion.
It will now be converted into a two-carbon compound called Acetyl CoA
Continuing the oxidation of the organic molecule
Pyruvate + CoA+ NAD+  Acetyl CoA + 2NADH + 2CO2

21. Stage 2: Acetyl CoA Formation

22. 9) Stage 3: Krebs Cycle Takes place in the matrix of mitochondria
AKA: citric acid cycle
Acetyl CoA created during step 2 now enters the Krebs Cycle
Complete oxidation of the organic molecule to carbon dioxide
2 Acetyl-CoA  4 CO2 + 6NADH + 2FADH2 + 2 ATP

23. Summary of Krebs Cycle:
Takes place in the mitochondrial matrix
Produces 6 NADH molecules
Produces 2 FADH2 molecules
4) Produces 4 CO2
5) Each glucose molecule sends 2 acetyl-CoA
through the cycle
6) Produces only 2 ATP molecules for each glucose

24. 10) Stage 4: Electron Transport Chain
Takes place on inner folds of mitochondria (cristae)
NADH & FADH2 are electron
carriers which transfer their
electrons to a succession of
membrane proteins on the inner membrane of the mitochondria
NADH  3ATPs
FADH2  2ATPs
This process releases energy
and helps form ATP molecules
Cytochromes

25. Stage 4: Electron Transport Chain
** Notice that the final
acceptor of the electrons
& Hydrogen is Oxygen.
Oxygen is a very strong
“electron grabber”
Hydrogen ions (H+) then
combine with the negative
charged oxygen atoms to
form water
** This process produces 34 ATP molecules

27. 11) Oxidative Phosphorylation:
AKA chemiosmosis
Actual mechanism by which ATP is produced
It uses the energy stored in the proton gradient to power the synthesis of ATP
Depends on enzyme ATP synthetase
As protons move through the ATP synthetase channel, part of the molecule turns and attaches phosphates to ADP molecules, forming molecules of ATP.
