Glycolysis
Where does glycolysis take place
What is the cytoplasm
Where does glycolysis occur
What is the mitochondrial matrix
Where does the ETC occur
What is the inner mitochondrial membrane
Name both of the mobile electron carriers used during cellular respiration
NAD and FAD
Is glycolysis aerobic or anerobic
Anerobic
Is the Krebs cycle aerobic or anerobic
Aerobic
Is the Krebs cycle aerobic or anerobic
Aerobic
What is another name for the Krebs cycle
The citric acid cycle
What is the net yield of glycolysis
2 ATP, 2 pyruvate and 2 NADH
What is the net yield of the Krebs cycle
Every one acytel coa produces 1 ATP, 3 NADH, 1 FADH2 and 2 CO2
What is the net yield of the ETC
36 ATP
True of False: When oxygen accepts electrons, water is produced as a by-product.
True
What is the name of the 3-carbon molecule produced at the end of glycolysis
Pyruvate
Is the Krebs cycle a cyclic cycle (meaning self renewing)
Yes
What is the name for the process of proton diffusion across the cellular membrane, creating an electrochemical gradient
Chemiosmosis
How do the products of glycolysis and Krebs cycle relate to the electron transport chain?
Glycolysis and the Krebs cycle produce the molecules that shuttle electrons to the electron transport chain
What are the steps of glycolysis (hint: there are
1. Glucose is phosphorylated
2. After many intermediate steps, ADP takes the phosphates from ATP, taking them off the glucose
3. 2 Pyruvate is formed
4. Pyruvate is converted into Acetyl CoA so that the Krebs cycle can begin
What are the steps of the Krebs cycle
1. Acetyl CoA enters the mitochondrial matrix
2. Citric acid is formed
3. Citric acid is repeatedly oxidized (losses electrons as a result that NAD+ and FAD+) will pick up
4. Oxaloacetate is formed, completing the cycle
What are the steps of the ETC
1. NADH enters the inner mitochondrial membrane and gives the first complex 2 electrons
2. The hydrogens pass through the membrane
3. FADH2 enters the inner mitochondrial membrane and gives the second complex 2 electrons
4. Hydrogens once again pass through the membrane
5. Complexes continue to accept electrons freely until complex 4
6. At complex 4, oxygen is required to accept electrons. As a result, water is a by product
7. The high electron concentration crosses the membrane through ATP synthase
8. 32 ATP molecules are produced
What is the primary purpose of cellular respiration?
To produce ATP
