AP Biology R-11 Essential Knowledge: Ch 9 Cellular Respiration 9.1 Catabolic pathways yield energy by oxidizing organic fuels To keep working, a cell must regenerate its supply of ATP Organic Compounds + Oxygen ? Carbon Dioxide + Water + Energy C6H12O6 + 6O2 ? 6CO2 + 6H2O + ATP Redox reactions involve the transfer of electrons The substance losing electrons is oxidized, the substance receiving electrons is reduced (LEO-GER or OIL RIG) The oxidizing agent is reduced; the reducing agent is oxidized During cellular respiration, glucose is oxidized to carbon dioxide, and oxygen is reduced to water Energy is released as electrons are transferred from organic compounds to oxygen (reduction releases energy); the energy is used to make ATP
