The function of oxygen in aerobic respiration is to:
a) carry hydrogen ions from the Krebs cycle to the electron transport chain
b) bind electrons and hydrogen ions at the end of the electron transport chain
c) attach a high energy phosphate group to ADP
d) form carbon dioxide in the Krebs cycle
e) donate electrons to NADH to make it release a hydrogen ion
Aerobic respiration uses oxygen to break down glucose, amino acids, and fatty acids and is the main way the body generates adenosine triphosphate (ATP), which supplies energy to the muscles.
