BIOL 215 CWRU ADVANCED PREP PACK
2026 FULL QUESTIONS AND CORRECT
ANSWERS
◉In cancer cells, increasing the amount of metabolites moving
through glycolysis makes it so. Answer: more metabolites are
available for the biosynthesis of other molecules
◉molecular biology/ chemistry of yogurt. Answer: Incubating lacto.
bacteria w milk at 110*F which carries out glycolysis and
fermentation- lactose is the energy source for glycolysis- high
temperature -> denature protein -> more acidic
◉FDG - PET. Answer: Imaging technique that exploits Warburg
effect, FDG uptake assess glucose uptake in cells to see cancer
◉'big picture' of chemotropic energy metabolism. Answer:
◉which type of human cell can carry out fermentation. Answer:
muscle cell
, ◉Why is fermentation economically important?. Answer: beer,
yogurt, wine, nail remover
◉Why is fermentation important for the cell?. Answer: convert
NADH -> NAD+ so glycolysis can continue
◉How is acetaldehyde converted to ethanol in ethanol
fermentation?. Answer: Acetaldehyde is reduced while NADH is
oxidized to produce ethanol and NAD+
◉What is the first product of ethanol fermentation pathway?.
Answer: 2 acetaldehyde molecules and 2 CO2 molecules
◉Why is NADH oxidized in lactate fermentation?. Answer:
◉What happens in lactate fermentation pathway?. Answer: Pyruvate
is reduced to lactate, while NADH is oxidized to NAD+.
◉Net ATP of aerobic respiration per glucose. Answer: 2 glycolysis, 2
TCA, 32-34 oxidative phosphorylation
◉Net ATP of glycolysis alone per glucose. Answer: 2
