Cellular respiration carried out in 2 stages:
Glycolysis and Oxidation
Slide3The equation for cellular respiration is the opposite of the equation
for photosynthesis
.
Slide4Slide5The products of Photosynthesis are the reactants of Cellular Respiration
Slide6Cellular respiration occurs in
2 main parts
.
1.
Anaerobic process = Glycolysis
Breakdown of Glucose
2. Aerobic respiration = Glycolysis, Krebs cycle, Electron Transport Chain
Production of ATP
Slide7Where does Respiration Happen?
In the Cytoplasm and MitochondriaPOWER HOUSE of THE CELL

Slide9Why Is Cellular Respiration Important?
To make ATPHigh Energy Bond between phosphates
Slide10Slide11How Does Respiration Work
Slide12Step 1: Glycolysis
Cytoplasm
Glucose
2
Pyruvate
Main Goal: To make
Pyruvate
ATP
Occurs in the CYTOPLASM
Slide13How glycolysis works…
2
molecules of ATP are used to create
2 molecules
of Pyruvate. A net gain of 2 ATP (4 ATP made, but 2 used) are created, plus 2 molecules of NADH are also produced.
Slide14Step 2:
Kreb’s Cycle
(Citric Acid Cycle)
Mitochondrial Matrix
2 pyruvate
Occurs in mitochondrial matrix

CO
2
Main Goal: To produce HEMs!
Slide15How does the Kreb’s cycle work?
The cycle goes around
TWO
times resulting in:
six
CO2 molecules, two ATP, eight NADH, and two FADH2.
Slide16Step 3: Electron Transport System (ETS)
Occurs in Inner Membrane of Mitochondria
Aerobic
: Uses
Oxygen
Main Goal: To make
lots of

Slide17Electron Transport Chain
NADH
and
FADH
2 are used to make ATP
There are FOUR electron transport systems that catalyze and generate ATP.
Have the capacity to donate or accept electrons.
Slide18Electron Transport Chain
The electrons combined with oxygen to produce H2
O
Oxygen known as the final electron acceptor, without it, the electron transport chain cannot work
Slide19Slide20How much ATP was made?Glycolysis = 2 ATPKrebs Cycle = 2 ATP
ETC = 34 ATP Cellular Respiration =38 ATP4
ATP needed
to start the process
net yield is 34 molecules
Slide21NO
OXYGEN is present:
Fermentation
Lactic acid fermentation
Alcohol fermentation
Anaerobic Respiration
Two main types:

Slide25Photosynthesis and Cellular Respiration Poster
Title (1pt)Show how molecules of Carbon, Hydrogen and Oxygen travel through each system. (6pts)
Reactions need to be written out in appropriate locations
(5pts)
Label all molecules/organelles/everything (2pt)Arrows are neatly placed and appropriate (2pt)Pictures should not need descriptions to show processes and connection between Photosynthesis and Cellular RespirationColor (1pt)Organization (2pt)Correct (1pt)
Slide26No Organelles
Slide27Too Basic, No Creativity
Slide28Good, But You Can Do Better!
