Enzyme transfers extracted electrons to NAD+, storing them as NADH

Hint 15

adds electrons

Front 16

Third Step in Citric Acid Cycle

Back 16

CoA is attached to acetate (by an unstable bond) forming acetyl CoA

Hint 16

Coenzyme attaches to something to form the final product

NADH

Front 22

How does ATP synthase use the flow of hydrogen ions to produce ATP?

Back 22

ATP synthase acts as a rotor which allows for the production of ATP from ADP +Pi by activating catalytic sites in the knob
