ETS

Electronic Transport System

QuestionAnswer

2nd step. What are passed from one energy carrier to the next> Electrons
3rd step. Energy is released with each transfer
4th step. This energy is used to pump ______ ions into the ______ ______ of the _______ hydrogen, outer compartment, mitochondrion
Most ATP is produced during? ETS
Most NADH is produced during? Krebs cycle
How do cells make energy? By pumping Hydrogen ions across a membrane.
ETS produces how many ATP? 32
Overall equation of CR C6H12O6 + 6O2 -> 6CO2 + 6H2O + 36 ATP + Heat

5th step. _____ _____ build up in the outer compartment (Higher concentration of ___+ ) Hydrogen ions
6th step. what happens during the sixth step? WHich enzyme is used? H= flow back across the membrane through enzyme (ATP synthase) that synthesizes ATP.
7th step. What happens ? Last protein passes electrons to oxygen and H+, generating water.
