Q

How do the electron transport chain and ATP synthase power cellular respiration?

A

The electron transport chain transports electrons to pump protons across the inner mitochondrial membrane. This drives the synthesis of ATP.

Q

How is oxygen consumed in cellular respiration?

A

Oxygen combines with electrons and two hydrogen ions to make water. Then hydrogen ions flow through ATP synthase and combine with ADP and phosphate group to form ATP.
