Biology Exam 2: Pyurvate Oxidation, Krebs Cycle

Oxidation of pyurvate takes and produces

1 3C pyurvate → 1 CO2, 1 NADH, 1 acetyl-CoA (enters krebs cycle)

citric acid cycle

acetyl-CoA + 3NAD+ + 1FAD + 1ADP + 1P + 2H2O → 2CO2 + 3NADH + 1FADH2 + 1 ATP + 3H +1 CoA

step one:

condensation forms citrate

step two: citrate →

isomerization makes isocitrate

step three: isocitrate →

oxidation one, alpha-ketoglutate (NAD+ → NADH)

step four: alpha-ketoglutate

oxidation two → succinyl CoA (NAD+ → NADH)

stage five: succinyl CoA →

s-lvl phos, succinyl CoA minus CoA → succinate

GDP → GTP » ADP → ATP

six: succinate →

oxidation three, fumarate

FAD → FADH2

seven: fumate

+H2O → malate

hydration

8: malate →

oxaloacetate

oxidation 4

mnemonic (products)

chimpanzees inspected apes purposefully after father made organatans

mnemonic

chimpanzees inspected 12 pink 3-horned 4s

Theoretical V Actual

36 ATP, 38 bacteria

1 NADH → 3 ATP

1 FADH2 → 2 ATP
