Key Concepts from Past Chapters
There is an overall ______ in free energy from the beginning to the end of cellular respiration.
Potential answers: increase, decrease
What is decrease?
What is the cytoplasm?
This is where (in the cell) pyruvate oxidation occurs.
What is the mitochondria?
or
What is the mitochondrial matrix?
This is where the citric acid cycle occurs in the cell.
What is the mitochondria?
What is the mitochondria?
FAD _____ electrons when it is converted to FADH2.
Possible answers: gains, loses
what is gains?
This 3-carbon molecule is one of the net outputs of glycolysis.
What is pyruvate?
This single carbon molecule is released during pyruvate oxidation.
What is CO2?
The citric acid cycle produces this molecule from the inputs ADP + Pi.
What is ATP?
These two electron carriers hand off electrons to the proteins of the Electron Transport Chain.
What are NADH and FADH2?
This molecule contains high energy bonds, which can power chemical reactions when broken.
What is ATP?
Of the net outputs, this is the electron carrier output from glycolysis.
What is NADH?
This is the electron carrier produced during pyruvate oxidation.
These are the net inputs of the citric acid cycle.
What are (1) acetyl-CoA, (2) NAD+, (3) FAD, and (4) ADP + Pi?
This is the location of the proteins of the Electron Transport Chain.
What is the inner membrane of the mitochondrion?
This molecule has the chemical formula of C6H12O6.
What is Glucose?
These are the net inputs of glycolysis.
What are glucose, ADP + Pi, and NAD+?
These are the three net inputs of pyruvate oxidation.
What are (1) pyruvate, (2) NAD+, and (3) Coenzyme A (CoA)?
These are the net outputs of the citric acid cycle.
What are (1) coenzyme A (CoA), (2) CO2, (3) NADH, (4) FADH2, and (5) ATP?
These are the net inputs for the electron transport chain.
What are NADH, FADH2, ADP + Pi, and O2?
Name one of the two major ways that cellular respiration makes ATP.
What is substrate-level phosphorylation?
or
What is oxidative phosphorylation?
These are the three phases of glycolysis.
1. Energy input / preparatory phase - consumes 2 ATP
2. Splitting glucose / Cleavage phase (6 C to two 3 C)
3. Energy payoff - produces 4 ATP and 2 NADH
These three molecules are the net outputs of pyruvate oxidation.
What are (1) Acetyl-CoA, (2) CO2, and (3*) NADH?
* NADH = electron carrier
What is (1) citrate, (2) isocitrate, (3) ketoglutarate, (4) succinyl-CoA, (5) succinate, (6) fumarate, (7) malate, or (8) oxaloacetate?
These are the net outputs for the electron transport chain.
What are NAD+, FAD, a lot of ATP, and H2O?
