Cellular Respiration Cellular respiration is the process in
which plants and animals convert FOOD into ENERGY (ATP!) in their cells. This occurs in the Mitochondria!
Energy is stored in the form of ATP!!
ADP – after ATP is broken down
Two types of respiration:
(1) Aerobic (uses O2) - Glucose is broken down to CO2 and water with the help of enzymes to produce ENERGY!!
3 stages of aerobic respiration Glycolysis
Citric Acid Cycle
Electron Transport Chain
(2) Anaerobic (doesn’t use O2) Glycolysis and Fermentation
It all starts with Glycolysis:
Where:
In cytoplasm of cells
Requires 2 ATP to
initiate & produces
4 ATP at the end
=net gain of 2 ATP
What:
Uses glucose from
ingestion or PS
& breaks it down
into pyruvate
This pyruvate can
be used in 2
ways…
Pyruvate moves into the mitochondria and is converted to acetyl-CoA
1st way: Aerobic RespirationOccurs in ALL eukaryotic organisms!
Occurs in the mitochondria of cells!
C6H12O6 + 6O2 6H2O + 6CO2 + 36 ATP
Why is the
Mitochondria
a good
structure
for Cellular
Respiration?
B/c high surface
area on highly
folded inner
membrane
allows for more
rxns to occur!
LEADS TO MORE
ATP!!!
Aerobic Respiration includes Citric Acid Cycle/Kreb’s Cycle: pyruvate is
modified and carbons from it bond to oxygen to
form carbon dioxide, which is released!
2 ATP made!
Electron Transport Chain: e- are transported,
energy is released & form 32 ATPs!
At the end of the chain, the extra Hs bond to
oxygen to form water!
Foldable Part 2 – Information about
Aerobic Respiration (Glycolysis, Krebs
Cycle, ETC)
Foldable will include who does it, what
is the process, where does it occur,
when does it occur, how does it occur
(i.e. organelle, different processes in
different parts of each organelle,
reactions, etc)

Aerobic Vs. Anaerobic Respiration
Aerobic Respiration – requires O2
Anaerobic Respiration – Does not require O2.
– Also called Fermentation – occurs in yeast, bacteria, and muscle cells of animals.
– This occurs in the cytoplasm of the cell!!
Think about bacteria…how are they different from all other organisms?
2 types of Fermentation Lactic Acid Fermentation
– Occurs in the muscle cells of animals
– Glucose Lactic acid + 2 ATP
– Sore muscles after exercise!
Alcoholic Fermentation
– Occurs in yeast
– Glucose Alcohol + CO2 + 2 ATP
– Used in alcohol production!
What is this???
