TCA Cycle
Metabolic reactions that break down molecules of acetyl CoA to
carbon dioxide and hydrogen; all energy yielding nutrients
(carbohydrates, lipids, and protein) go through the TCA cycle
for energy
Electron Transport Chain
(ETC)
Electrons from hydrogen are passed to oxygen and the energy
released is trapped in the bonds of ATP; low-energy electrons
with the remaining hydrogen atoms combine with oxygen to form
water (which is why oxygen is essential to life) |
