Aerobic Respiration
|
Combustion of Glucose:
Glucose + O2 --> CO2 + H20 |
|
Where does glycolysis take place?
|
In the cytosol, and it doesn't require oxygen (but it's not poisoned by oxygen either)
|
|
Overall reaction for glycolysis
|
Breaks down glucose to produce: net 2 ATP, 2 NADH, 2 (3-carbon pyruvates)
|
|
Fermentation
|
-If cell can't use oxygen, after glycolysis, the NADH = oxidized back to NADH+, and carbons are removed from pyruvate to make CO2 and EtOH in yeast, or lactic acid in other cells
|
|
Where do the products of glycolysis go?
|
Mitochondrian
|
|
Respiration inside the Mitochondrian
|
-Each NADH produces 3 ATP's via electron transport chain
-Each pyruvate is converted to an acetyl COA, which transfers 2 carbons to oxaloacetate to make citrate, which begins the krebs cycle |
|
Citric Acid Cycle
|
-Makes 1 ATP, 3 NADHs, 1 FADH
|
|
Each NADH makes ________ ATP's via electron transport chain
|
3
|
|
Each FADH makes _________ ATP's via electron transport chain
|
2
|
|
_______ pyruvate results in _______ turn(s) of the krebs cycle
|
1:1
|
|
Aerobic Respiration of a single glucose molecule results in how many net ATP's?
|
36 ATP's
|
|
The Electron Transport Chain
|
-Series of proteins called cytochromes which are embedded in inner membrane of mitochondrian
-Pass down high energy electrons from one protein to next, use energy of electron to pump protons into intermembrane space, resulting in low pH -ATP synthase allows protons to flow back into matrix, uses electrochemical gradient to produce ATP |
|
What is the final electron acceptor in the electron transport chain?
|
oxygen
