Unformatted text preview: t slide Glucose + 6O2 ----> 6CO2 + 6 H2O
2 H2 + O2 ----> 2 H2O
CH4 + 2O2 ----> CO2 + 2H2O
∆ H iis negative (heat energy is
Reaction is exothermic Glucose + 6 O2 <---- 6 CO2 + 6 H2O ∆ H is Positive
Entropy is decreasing !
Reaction is endergonic Summary: organisms utilize
redox reactions with - ∆ G
(metabolism) to produce high
energy electrons. Reactions: reactants and products
• If the C (carbon) in an organic
reactant molecule gains electrons,
it is reduced
• If the C in an organic reactant
molecule looses electrons, it is
oxidized Fig 2.20: burning methane (CH4)

reduction of Carbon compounds:
