Campbell's Biology, 9e (Reece et al.) Chapter 9 Cellular Respiration and Fermentation This is one of the most challenging chapters for students to master. Many students become overwhelmed and confused by the complexity of the pathways, with the multitude of intermediate compounds, enzymes, and processes. The vast majority of the questions in this chapter address central concepts rather than details of these pathways. Other questions have accompanying figures that provide details for reference and ask students to interpret or use these models. Overall, the emphases are on the inputs and outputs of each pathway, the relationships among these pathways, the cellular locations, redox as a central principle in respiration, and chemiosmosis.

Lecture Presentations byNicole Tunbridge and Kathleen Fitzpatrick Chapter 10 Photosynthesis 1 The Process That Feeds the Biosphere Plants and other photosynthetic organisms contain organelles called chloroplasts Photosynthesis is the process that converts solar energy into chemical energy within chloroplasts Directly or indirectly, photosynthesis nourishes almost the entire living world Photosynthesis occurs in plants, algae, certain other unicellular eukaryotes, and some prokaryotes ? 2017 Pearson Education, Inc. 2 Autotrophs are ?self-feeders? that sustain themselves without eating anything derived from other organisms Autotrophs are the producers of the biosphere, producing organic molecules from CO2 and other inorganic molecules

Cellular Respiration Stage 4: Electron Transport Chain Cellular respiration What?s the point? The point is to make ATP! ATP ATP accounting so far? Glycolysis ? 2 ATP Kreb?s cycle ? 2 ATP Life takes a lot of energy to run, need to extract more energy than 4 ATP! A working muscle recycles over 10 million ATPs per second There?s got to be a better way! I need a lot more ATP! There is a better way! Electron Transport Chain series of proteins built into inner mitochondrial membrane along cristae transport proteins & enzymes transport of electrons down ETC linked to pumping of H+ to create H+ gradient yields ~36 ATP from 1 glucose! only in presence of O2 (aerobic respiration) O2 That sounds more like it! Mitochondria Double membrane outer membrane inner membrane

AP Biology Name ____Ryan Hanssens_______ Chapter 9 Guided Reading Assignment ?Hint: review the concept check questions ? these are great quick quiz questions!? Define the two catabolic pathways: Fermentation ? a partial degradation of sugars that occurs without the use of oxygen? Cellular respiration ? when oxygen is consumed as a reactant along with the organic fuel; most efficient catabolic pathway; mitochondria house most of the metabolic equipment needed ??

Mitochondria and Oxidative Phosphorylation Controlled oxidation of sugars Breaks down sugar in a number of small stepwise events = more efficient NADH and FADH2 carry energy in the form of high energy electrons Produce these molecules as a way to transport high energy electrons (Energy is stored as redox potential) These electrons will be transferred to the electron transport chain Glycolysis occurs in a stepwise process NADH is an energy carrier (energy will be harvested later) Some ATP is produced directly Most of the energy is still stored in pyruvate molecules Citric acid/tricarboxylic acid/Krebs cycle Oxidize pyruvate Yield for every 2 molecules of acetyl CoA: 2 GTP + 2 FADH2 + 6 NADH + 4 CO2
