CELLULAR RESPIRATION
Let’s take a look back!
– Photosynthesis: ________________________________________________
•
Occurs only in plants or organisms with plastids like chlorophyll
•
Carbon dioxide is taken in
•
Oxygen is ____________________________
•
Also requires light & H2O
Cellular Respiration: chemical process where carbohydrates are broken down to be a quick source of ____.
– Location: mostly within mitochondria, first part in cytoplasm
– ______________________________
•
______ Types:
1. Aerobic: _____________________________
2. Anaerobic: ___________________________

____ Stages:
1. Glycolysis
2. Citric Acid Cycle (Krebs Cycle)
3. Electron Transport Chain
•
Three Stages:
1. Glycolysis = _________________________
2. Citric Acid Cycle = ____________________
3. Electron Transport Chain = _____________
1. Glycolysis: _______________________________________________________________
•
Occurs in ____________________
•
Costs 2 ATP to START reaction
•
Breaks _______________________________________________________ (pyruvate) (goes to
Krebs Cyele)
•
Makes total of ____ ATPs
•
At end of reaction, net of 2 ATP available to cell, and
NADH
•
_______________________________________
2. Citric Acid Cycle (Krebs Cycle)
•
Occurs in __________________________ (matrix: space enclosed by inner membrane)
•
______________________
•
2 cycles occur at the same time (1 for each pyruvate)
•
Each cycle produces _____ ATP
•
Yields (_______________):
1. _____________________
2. _________ & __________
-Go to ETC
3. _____________________
-Released as waste
3. _______________________________________________________________
Takes place in and across inner mitochondrial membrane.
•
NADH from glycolysis & Krebs and FADH2 from Krebs unload
electrons at ETC. Energy is used to make ATP.
•
Result: __________________________________
•
•
__________________________
END RESULT OF RESPIRATION:
– ____________________________________________________
– Oxidative Phosphorylation

•
____________________________________________________________
•
ADP is converted to ATP by adding a phosphate group.
•
But wait! What if there was not enough oxygen? Could cellular respiration still have taken
place?
•
_______! Anaerobic Respiration or ___________________________ takes place!
FERMENTATION
– ___ Kinds:
1. ___________________________
2. ___________________________
– Both kinds ______________________________________________
– How many ATPs does that mean they make? ______ ATPs
1. _________________________ Fermentation
– ___________________
– Produces burning feeling in muscle cells
– Occurs when body is worked to the point that more oxygen is being used than taken in
– Produces __________________________________________________________
2. _________________
– ______________________
– Carried out by some bacteria and yeast
– Used to bake bread and make wine
– Produces _____________________________________________________
