Glycolysis
This is the location in the cell where glycolysis occurs.
What is the cytosol (or cytoplasm)?
This is where the Krebs cycle takes place in the cell.
What is the mitochondrial matrix?
This is the specific location of the electron transport chain in the mitochondrion.
What is the cristae?
This is the only stage of cellular respiration that occurs during fermentation.
Glycolysis
This is what the acronym ETC stands for.
What is the electron transport chain?
This is the net ATP gain from glycolysis.
2
These are the three energy products generated per turn of the Krebs cycle (must name all three for full credit).
What are ATP (or GTP), NADH, and FADH₂?
This molecule serves as the final electron acceptor at the end of the electron transport chain.
What is oxygen?
These are the two main types of fermentation.
What are alcohol (alcoholic) fermentation and lactic acid fermentation?
These are the reactants used to make ATP.
What are ADP and P?
Glycolysis splits one 6-carbon glucose molecule into this many 3-carbon molecules.
What is pyruvate?
This is the number of times the Krebs cycle must turn to completely process one glucose molecule.
What is 2?
This is the name of the enzyme that uses the proton gradient to synthesize ATP.
What is ATP synthase?
This is the main reason cells undergo fermentation when oxygen is unavailable.
What is to regenerate NAD⁺ (so glycolysis can continue
This is the transition molecule that connects glycolysis to the Krebs cycle, formed when pyruvate loses a carbon as CO₂.
What is acetyl coA?
This is the molecule reduced during glycolysis from one glucose molecule.
What is NADH?
This is the total number of CO₂ molecules released after both turns of the Krebs cycle for one glucose.
What is 4?
This is the type of transport occuring during chemiosmosis.
What is facilitated diffusion?
In the fermentation that occurs in muscles cells, pyruvate is reduced to this molecule while NADH is oxidized to NAD⁺.
What is lactic acid?
This type of phosphorylation occurs when enzymes directly transfer a phosphate group from a substrate to ADP, producing about 1/8 of the total ATP in cellular respiration.
What is substrate level phosphorylation?
The enzyme phosphofructokinase catalyzes the rate-limiting step of glycolysis and is allosterically inhibited by ATP and citrate, demonstrating this type of cellular regulation.
What is negative feedback (or feedback inhibition)?
This is the 6 carbon molecule first formed in the Kreb cycle. Hint: Also another name for the Kreb cycle
What is citric acid cycle
This is the location of the mitochondria that has the lowest pH.
What is the intermembrane space?
During fermentation, pyruvate must be reduced to regenerate NAD⁺ because this stage of cellular respiration cannot occur without oxygen, leaving NADH with nowhere to deposit its electrons.
What is the electron transport chain?
Cyanide is a deadly poison because it blocks the final protein complex in the electron transport chain, which would cause this to happen to the proton gradient and ATP production.
What is the proton gradient would collapse (or dissipate) and ATP production would stop (or drastically decrease)?
