Answer 7

-The matrix

Question 8

Answer 8

NADH

Question 9

The reduction of oxygen to water uses the intermediate generated from _____ and the ____, NADH. This will produce_____

Answer 9

• Glycolysis
  -Kreb’s Cycle
  -ATP

Question 10

Where does the reduction of water occur

Answer 10

• In the cristae of the mitochondria and occurs in the electron of the transport chain

Question 11

What is ATP generated by?

Answer 11

the creation of a H+ gradient between cristae or inner mitochondrial membrane (cristae) and the outer mitochondrial
membrane.

Question 12
