cellular respiration

• the parts of cellular respiration: glycolysis, Krebs cycle, intermediate step, electron transport chain
• glycolysis- breaks down glucose
• Krebs cycle- citric acid cycle: metabolic fork in the road, completes the break down of glucose
• Intermediate step- pyruvate oxidation
• ETC- electron transport chain- oxidative phosphorylation- ATP synthesis
• equation for cellular respiration: glucose + oxygen --> carbon dioxide + water + energy (C6H12O6 +6O2= 6CO2 + 6H2O = ENERGY +ATP).
• numerical equation for cellular respiration: C6H12O6+6O2= 6CO2 +6H2O+ ENERGY+ATP
• oxidation- looses electrons
• reduction- gains electrons
• leo (loosing electron oxidation) says grr (gaining electrons reduction)
• glucose is oxidized in cellular respiration
• electron carriers NAD+ and FAD+ are reduced to NADH and FADH2
• catabolic process- exergonic reaction, energy is released, ATP is produced
• anabolism- endergonic reactions, energy is required, ATP is used
• redox reaction- reduction of one substance so that another substance can be oxidized
• NADH can be used in all on the steps
