How many ATP are produced in one turn of ATP synthase?
3
What is the redox value of NAD/NADH?
-300mV
How many irreversible steps are in gluconeogenesis?
4
What energy carrier is most commonly used in Krebs?
NAD/NADH
What pathway of PP is irreversible?
oxidative pentose phosphate
How many protons are pumped from NADH running through the ETC

What is the deltaE of the succinate to fumarate using Q/QH2 as an energy carrier?
0mV
What is the purpose of the committed step of glycolysis?
trap sugar molecule inside cell once cleaved
What is the name of the Krebs enzyme that is also used in the ETC?
succinate dehydrogenase / complex 2
What PP process would be run to produce only NADH, but no R5P
oxidative followed by nonoxidative
Explain the Q cycle
i dont wanna type this out
What is the E value for an alcohol/carbonyl?
-300mV
Describe how gluconeogenesis converts pyruvate to high energy PEP
Addition of CO2 via bicarbonate and ATP, then GTP used to release massive amounts of energy!
Describe how a thioester is attached in step 4
carbanion mechanism: stabilization via thiamine as carbanion attacks sulfur of lipoic acid. molecule gets oxidized, thioester forms, the sulfur of lipoic acid and CoA swap
How many G6P molecules are needed to run nonoxidative PP?
5!
Explain why different organisms have different amount of ATP generation through ATP synthase
c subunits - i also don't wanna type this
