BIO 111 EXAM 2 Questions and Answers with Verified Solutions |
Latest 2026 Update
Q: Krebs cycle
Answer:
happens in mitochondrial matrix; acetyl-CoA goes in and 2 CO2, 3 NADH from
NAD+, 1 FADH2 from FAD, 1 ATP from ADP +Pi (ultimately 12 ATP)
Q: electron transport chain
Answer:
happens in cristae membrane; 10 NADH and 2 FADH2 go in and 36
ATP are produced (theoretically)
Q: amount of ATP produced in cellular respiration
Answer:
actual 30 ATP and the energy loss is from
"leaky" inner membrane and use of the proton gradient created for other things
(creating heat
in brown fat)

Q: feedback inhibitors of glycolysis
Answer:
NADH (inhibits pyruvate dehydrogenase) and ATP (inhibits
citrate synthetase) which is why fermentation is important for breaking those
molecules down
to either lactate or ethanol
Q: catabolism of fats
Answer:
broken down to fatty acids and glycerol which are then converted to
acetyl groups to enter Krebs cycle and it has 20% more yield
Q: photsynthesis equation
Answer:
6CO2 + 6H20 --> C6H12O6 + 6O2 + 6H2O

Q: stoma
Answer:
gets CO2 in and O2 out of cell
Q: light-dependent reactions
Answer:
occur in thylakoid membrane and capture light energy and water
to make ATP, NADPH, and oxygen
Q: light-independent reactions (calvin cycle)
Answer:
occur in stoma and use energy (from ATP and
NADPH) and CO2 (from air) to make ADP, Pi, and NADP+
