EXTENDED RESPONSE
Choose one 5 pointer
• 1. Trace a NAD+ to NADH and back.
• EXAMPLE: NAD+ is reduced (to NADH) in
the Krebs cycle and delivers e- and H+ to
the first ETC protein complex. Here the eare given to the ETC and the H+ cross the
IM. The NAD+ formed goes back to the
Krebs cycle and picks up e- and H+ and
citric acid is broken down.
EXTENDED RESPONSE
Pick one 5 pointer
• 2. The ETC will move electrons down the
electron transport chain from high energy
to lower.
• The e- are pulled toward oxygen, the final
electron acceptor, to form water.
•
• As the e- are removed the H+ ions from
NADH collect in the inner membrane
space.
• As these H+ move through the ATP
synthase, enough energy is made to the
moving enzyme to cause a P to join ADP
to form ATP.
