Updated Final Exam Study Guide The final is on Friday May 9 at 5:30 PM in Campbell Auditorium Bring your LSUID and pencil 81 questions worth 2 points each (Note that the highest score in SB will be 108% - not 162) Biological molecules – 3 questions Condensation (dehydration) synthesis- proceeds with the removal of a water molecule; synthesis of fat Fat is made of up one monomer of glycerol and 3 molecules of fatty acid Carbohydrate structure and function play an important role in energy (C 6 H 12 O 6 ) - Metabolic fuel storage form ( starch-plants , glycogen- humans ) Structural roles- cellulose in plants - support the structure Chitin in animals - Polymer of glucose structured protein Lipid structure water insoluble organic biological molecules made up of nonpolar groups- water doesn’t react well - Saturated - (butter) - no H double bonds between adjacent Carbons -Unsaturated- (olive oil) - double bonds lower melting point Chapter 5 Figures 5.6, 5.8, 5.11 and 5.12 Respiration and Photosynthesis  – 4 questions See review sheet and work sheet on these topics on BB under Course Documents. Respiration has 2 phases 1. Cytoplasm - Glycolysis- Investment Phase of 2 ATP 2. Mitochondria - Krebs CAC, Oxidative Phosphorylation/ Electron Transport- Production of ATP (4) End of Glycolysis is ; pyruvate is the branch point FADH 2 and NADH carry electrons in electron transport chain 3 ATP are produced per NADH     2 ATP are produced per FADH 2 Glucose as a starting material invests more ATP Glycogen as a starting material is more beneficial because it only needs 1 ATP resulting in 3 ATP in the end At the end of light reactions : ATP, NADPH, and oxygen Calvin Benson Cycle- light independent reaction; uses CO 2 to make sugar in the stroma of the chloroplasts; CO 2 combines with RuBP PS I & II- In the thylakoid membrane C3 plants are normal What’s the relationship between photosynthesis and respiration? -Photosynthesis- uses light energy to produce complex organic molecules -Respiration utilizes these organic molecules to produced ATP, CO 2 and water for photosynthesis C4 plants corn, sugar cane; in hot regions CAM- succulent plants, cacti, pineapples, take up CO 2 at night and store as acids during the day Mitosis and Meiosis  – 4 questions Anaphase I- separation of homologous chromosomes Anaphase II – separation of sister chromatids 1

S phase is the synthesis of DNA Number of chromosomes Mitosis produces daughter cells with 2n number of chromosomes -identical to mother cell (same amount of DNA) Meiosis produces 1n number of chromosomes ( ½ of what it started with) Meiosis I- separation of homologous chromosomes Meiosis II- separation of sister chromatids DNA synthesized at S phase (between G1 & G2) For a diploid cell containing 8 chromosomes the completion of mitosis is the formation of daughter cells contains 8 chromosomes
