2 ATP
What are the by-products of the Kreb’s Cycle?
CO2 and Hydrogen
What is the main function of the Electron Transport Chain (ETC)?
Produce ATP by passing electrons down a chain
How many ATP are produced in the Electron Transport Chain?
34 ATP
What happens to hydrogen ions in the ETC?
They combine with oxygen to produce H2O
