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
