“Cellular Respiration: Harvesting Chemical Energy” Chapter 9
I. Two Basic Steps in Cell Respiration A. Glucose is Oxidized B. ATP Synthesized
II. Redox Reactions A. Oxidation: B. Reduction: Xe- + Y ==> X + Ye- a. C6H12O6 + 6O2 ==> 6CO2 + 6H2O + ATP
II. Redox Reactions A. Oxidation: B. Reduction: Xe- + Y ==> X + Ye- a. C6H12O6 + 6O2 ==> 6CO2 + 6H2O + ATP
III. Electron Acceptor Molecules - Electron Carriers A. NAD+ (nicotinamide adenine dinucleotide) 1. Characteristics -coenzyme of dehydrogenase -electron carrier 2. Function -oxidizing agent -2 H from glu => NAD+ => NADH
III. Electron Acceptor Molecules - Electron Carriers B. FAD (flavin adenine dinucleotide) -FADH2 -less energy than NADH
IV. ATP Synthesis - Two Methods A. Oxidative Phosphorylation -90% of ATP -via ETC -O = Final Electron Acceptor
IV. ATP Synthesis - Two Methods B. Substrate-Level Phosphorylation -enzyme – Pi => ADP
V. The Process of Cellular Respiration A. Oxidation of Glucose 1. Glycolysis - “Splitting of Glucose” -Glu split => two 3C molecules -w/ or w/out O2 -cytosol
V. The Process of Cellular Respiration A. Oxidation of Glucose 1. Glycolysis - “Splitting of Glucose” a. Two Phases of Glycolysis 1) Energy Investment Phase -2 ATP 2) Energy Payoff Phase -4 ATP -substrate level
V. The Process of Cellular Respiration A. Oxidation of Glucose 2. Junction/Transition between Glycolysis and Kreb’s Cycle (O2 present) a. Pyruvate => Mitochondria 1) COO- removed 2) 2C oxidized by NAD+ ==> Acetate 3) CoA attaches ==> Acetyl CoA
V. The Process of Cellular Respiration A. Oxidation of Glucose 3. Kreb’s Cycle -matrix -completes oxidation of glucose -NCFA 3211
V. The Process of Cellular Respiration A. Oxidation of Glucose 3. Kreb’s Cycle
V. The Process of Cellular Respiration B. Synthesis of ATP (by Oxidative Phosphorylation) -34 ATPs 1. Electron Transport Chain -cristae; many copies -NADH 2 electrons => Flavoprotein -2e- down chain, releasing energy -O = FEA => H2O
V. The Process of Cellular Respiration B. Synthesis of ATP (by Oxidative Phosphorylation) 2. Chemiosmosis -Energy Coupling a. ATP Synthase -powered by flow of H+
V. The Process of Cellular Respiration B. Synthesis of ATP (by Oxidative Phosphorylation) 2. Chemiosmosis b. Process of Chemiosmosis 1) ETC energy pumps H+ - matrix => intermembrane space => “Proton Motive Force” 2) H+ diffuse thru ATP synthase -ADP => ATP
V. The Process of Cellular Respiration C. Summary of Cellular Respiration
V. The Process of Cellular Respiration C. Summary of Cellular Respiration 1. Oxidation of Glucose 2. ATP Synthesis a. Substrate-Level Phosphorylation b. Oxidative Phosphorylation
V. The Process of Cellular Respiration C. Summary of Cellular Respiration 3. Flow of Energy
VI. Fermentation -Anaerobic -Glycolysis + Recycling of NAD+ -2 ATP - SLP
VI. Fermentation A. Two Types of Fermentation 1. Alcohol Fermentation (yeast, bacteria) -yeast, bacteria -Pyruvate ==> Acetylaldehyde ==> Ethanol
VI. Fermentation A. Two Types of Fermentation 2. Lactic Acid Fermentation -Pyruvate ==> Lactate -no CO2 -muscle cells, bacteria
VI. Fermentation B. Comparing Fermentation and Cellular Respiration • -glycolysis • -NAD+ • 1. Fermentation • -NADH electrons to organic molecule • -2 ATP • 2. In Respiration • -NADH electrons to O2 • -34 to 38 ATP
VI. Fermentation B. Comparing Fermentation and Cellular Respiration 3. Facultative Anaerobes: (yeast, some bacteria) -fermentation or respiration
