Unformatted text preview: t slide Glucose + 6O2 ----> 6CO2 + 6 H2O Glucose or 2 H2 + O2 ----> 2 H2O or CH4 + 2O2 ----> CO2 + 2H2O ∆ H iis negative (heat energy is s released !) released 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 reactants products • If the C (carbon) in an organic If reactant molecule gains electrons, it is reduced it reduced • If the C in an organic reactant If molecule looses electrons, it is molecule oxidized oxidized Fig 2.20: burning methane (CH4) burning Thinking about oxidation and Thinking reduction of Carbon compounds: reduction (CH2O)6 +...
