What is the chemical equation for cellular respiration?
|
C6H12O6 + 6(O2) ---> 6(CO2) + 6(H2O) + energy
|
|
|
What gets put in and produced in glycolysis?
1. 2. 3. 4. 5. |
1. 2 ATP put in
2. 2 PGAL produced... then convert 3. 2 NADH produced 4. 4 ATP produced 5. 2 pyruvate formed |
|
|
What gets put in and produced in the aerobic pathway starting from pyruvate through the Krebs cycle?
(multiply the following by 2 to get total) 1. 2. 3. 4. 5. 6. 7. 8. |
Multiply the following by 2 to get the total
1. Pyruvate put in 2. 1 CO2 + 1 NADH + 1 acetyl CoA produced 3. Acetyl CoA ---> citrate 4. Get 3 NADH 5. Get 1 FADH2 6. Get 1 ATP 7. Get 2 CO2 8. Get OAA |
|
|
How much FADH2, NADH, and ATP is produced in each of these processes (do the total... i.e. 2 turns of the Krebs cycle)
Glycolysis Pyruvate to acetyl CoA Krebs cycle |
Glycolysis: 2 ATP, 2 NADH---(4ATP)
pyruvate to acetyl CoA: 2 NADH---(6 ATP) Krebs cycle: 2 ATP, 6 NADH---(18 ATP), 2 FADH2---(4 ATP) Total: 36 ATP |
|
|
Where does oxidative phosphorylation take place?
|
Inner membrane of the mitochondria
|
|
|
Where does glycolysis occur?
|
Cytosol
|
|
|
Where does the Krebs cycle and the conversion of pyruvate to acetyl CoA occur?
|
Mitochondrial matrix
|
|
|
What's the difference between oxidative phosphorylation and substrate level phosphorylation?
|
Substrate level phosphorylation: A phosphate group is added to ADP to form ATP. The energy is transferred from the substrate molecule.
Oxidative phosphorylation: the phosphate group is added to ADP to form ATP, but the energy comes from the electron transport chain. A H+ gradient is made, which powers ATP synthetase |
|
|
What would happen if there wasn't any oxygen at the end of the electron transport chain?
|
NADH would accumulate. Once all of the NAD was used up, ATP would stop being made and the cell would die. Glycolysis and the Krebs cycle need NAD to run
|
|
|
Where does anaerobic respiration occur?
|
In the cytosol
|
|
|
What kind of organisms use alcohol fermentation?
|
Fungi (yeast), plants, and bacteria
|
|
|
What are the steps of alcohol fermentation?
|
1) Pyruvate ---> 1 CO2 + 1 acetylaldehyde
2) Acetylaldehyde + NADH ----> Ethanol + NAD |
|
|
What organisms does lactic acid fermentation occur in?
|
Humans and animals
|
|
|
What are the steps of lactic acid fermentation?
|
Pyruvate + NADH ----> lactic acd + NAD
|
|
|
What is chemiosmosis?
|
It's when you make ATP by using a proton concentration gradient
