How can cyanide affect cellular respiration?
Press to flip
Cyanide can inhibit the electron transport chain, preventing ATP synthesis.
Where does glycolysis occur within the cell?
Cytoplasm
What is one of the key differences between aerobic respiration and fermentation?
Fermentation occurs without oxygen and is less efficient in producing ATP.
What role does oxygen play in the Electron Transport Chain?
Oxygen acts as the final electron acceptor, forming water.
What are the products of glycolysis?
2 Pyruvate, 2 ATP, 2 NADH
What are the products of the Krebs Cycle for one glucose molecule?
2 ATP, 6 NADH, 2 FADH2, CO2
What is the primary energy currency of cells?
ATP (Adenosine Triphosphate)
What does NADH and FADH2 do during cellular respiration?
They transfer electrons to the electron transport chain.
What is the range of estimated ATP yield per glucose molecule in aerobic respiration?
30-38 ATP
Why is mitochondrial research important?
To understand mitochondrial diseases and their impact on cellular energy production.
How does the Electron Transport Chain generate ATP?
By creating a proton gradient that powers ATP synthase through chemiosmosis.
During which step of cellular respiration is Acetyl CoA produced?
During the intermediate step when pyruvate is transported into the mitochondria
What is the significance of the proton gradient in ATP production?
It drives ATP synthase to convert ADP to ATP during chemiosmosis.
In which part of the mitochondria does the Krebs Cycle occur?
Mitochondrial matrix
Which cellular structure is primarily involved in aerobic respiration in eukaryotic cells?
Mitochondria
