Flashcard 668: FADH2 electrons (e.g., from the TCA cycle) are transferred to _____ of the ETC, also known as succinate dehydrogenase
Answer: complex II
Extra: Complex II (succinate dehydrogenase) transfers electrons from FADH2 to coenzyme Q (ubiquinone). Because it bypasses Complex I, fewer protons are pumped, leading to less ATP production (1.5 ATP per FADH2 vs 2.5 ATP per NADH).
Note: Electrons from glycolysis enter the mitochondria via shuttles. The **glycerol-3-phosphate shuttle** also uses FADH2 to transfer electrons to the ubiquinone pool, which is why it shares the same energetic yield as Complex II.
Flashcard 669: Leydig cells do not contain the steroid hormone enzymes _____ or _____ and, therefore, cannot synthesize glucocorticoids or mineralocorticoids
Answer: 21β-hydroxylase
