Front Back
What happens during the Krebs cycle?
Pyruvic acid is broken into carbon dioxide in a series of reactions
How are high energy electrons used by the electron transport chain?
To convert ADP into ATP
Aerobic
Things that require oxygen
Example:Pathways of cellular respiration
Krebs cycle
Second stage of cellular respiration, pyruvic acid is broken down into CO2 in a series of energy extracting reactions
Electron transport chain
Electrons are passed to these during the krebs cycle. Uses these electrons to convert ADP into ATP
