BSC 197 Review Session This is an informal list of things discussed at review session Main topics to study Photosynthesis Respiration Virus structure Viral replication steps How influenza affects people Genome of a retrovirus RNA genome 9 DNA genome once inside host cell Difference between cyclic and noncyclic flow Cytoskeleton good description in my study guide Cell Surfaces protective gain information move material assessing how your neighbor cell is doing Electron Excitation chlorophyll gets hit by photon electron becomes excited quickly goes back down to base state giving off a red photon of light In a photosystem the electrons bounce off one another The special chlorophyll pair is used to grab electrons in their excited state Noncyclic Electron Flow Noncyclic because we can track the same electrons through the whole process 1 Electrons become excited in photosystem II Photosystem replenishes by degrading water 2 Electrons are picked up by primary acceptor 9 Pq 3 Cytochrome complex 9 Pc 4 Photosystem 9 Primary acceptor 9 Fd 9 NADP reductase 9 NADPH Cyclic Electron Flow I highly recommend referring to Dr Nichols s powerpoint 15 9 slides 14 amp 15 for this Cyclic electron flows differs from noncyclic in that we cannot track an electron throughout the process like we can in noncyclic Tight junctions act as stoppers on the basal lateral near the apical surface Desmosomes span cell membranes and anchor intermediate filaments Gap junctions tubes between adjacent cells that allow cells to communicate through cytoplasmic streaming Respiration Input glucose or another carb Output ATP 34 total ATP per glucose C02 waste water vapor With the exception of sunlight the outputs of respiration are the inputs for photosynthesis Fibronectin connectoradapter in ECM acts as a gobetween Diagrams to know Noncyclic electron flow Dr Nichols said to understand the goals of both electron flow types their inputs and outputs Expect a few questions on each cycle Cyclic electron flow spent a lot of time on electron flow Photosynthesis Cellular Respiration He mentioned these specifically I would recommend trying to learn as many as you can Study tip write and rewrite them so you draw them on the test Cyclic electron flow results in more ATP than NADPH 1 of each molecule and then an extra ATP Calvin cycle I give a more in depth view of each stage in my study guide Check it out 1 Carbon fixation 2 Reduction 3 Regeneration Main chemicals C02 RuBP Rubisco most abundant enzyme output GBP 2 GBP molecules ATP NADPH is used to carry out reduction and ATP is used to carry out phosphorylation Virus Structure Capsid Genome can be RNA or DNA Some have an envelope Leave by exocytosis always if enveloped lysis quotblowing cell up Respiration Regulation Turned on with the indication of cyclic AMP universal sign of stress in cells ATP turns cell quotof Glycolysis takes place in cytosol Oxidation occurs in Mitochondrion ETC occurs in inner membrane More on Cellular Respiration taken from my Study Guide also available on Study Soup Glycolysis Energy Investment phase 2 ATP 9 isomerase converts glucose to fructose 9 2 molecules of glyceraldehyde gt Energy Payoff phase glyceraldehyde phosphate gt 2 NADH molecules produced gt phosphates lost gt 4 ATP molecules gt pyruvate pyruvate enters mitochondrion gt Acetyl CoA and CO2 gt Krebs Cycle completes oxidation of organic molecules gt high energy electrons are saved in the form of 3NADH and FADH2 each cycle there are good diagrams of the cellular respiration cycle in Dr Nichols powerpoint presentations I Electron Transport Chain NADH and FADH2 are used in ETC gt electron from NADH gt reduces flavoprotein gt electron passed to highly electronegative molecules and reduces acceptor and oxides donor gt electron is accepted by Oxygen molecule Blue colored sentences denote transitional steps in Cellular Respiration Cytoplasmic Response a limited response that turns onoff a protein Nuclear Response slower but more widespread because you are turning off the genome sequence Biological Energetics Autotrophs make their own food mainly photosynthetic need many autotrophs to survive Heterotrophs the further removed from autotrophs the less efficient you become must eat others for energy High energy electrons are stored in Krebs cycle 9 electrons are passed through ETC 9 used to power pumps that establish a gradient using protons 9 protons must pass through rotor causing rotor to spin and the enzymatic knob powers reaction to make ATP
