BIOL 1107 1nd Edition Lecture 37 Outline of Last Lecture I Darwin and His Observations and Inferences II Evidence of Evolution III DNA Sequences Predictions Outline of Current Lecture I Final Exam Review Qs Current Lecture I Final Review Questions 1 What three types of atoms are found in all carbs Carbon oxygen hydrogen 2 What type of interactions between all nonpolar molecules London dispersion 3 What are four elements that make up 96 of living things Carbon nitrogen oxygen 4 Class of molecules that can most easily pass lipid bilayer without help Small nonpolar 5 Describe structure of starch Is it di mono polysaccharide Polysaccharide 6 What are the 3 parts of a nucleotide Nitrogenous base pentose sugar and phosphate group 7 What is osmosis Transport of water across a membrane towards high solute concentration 8 A molecule is said to be amphipathic What does this mean Hydrophobic hydrophilic 9 Two electrons share unevenly Polar 10 Functional groups acidic Carboxyl 11 Building blocks of proteins How many types exist Amino acids 20 12 Co transporters no ATP energy where does energy come from Concentration gradient of another ion 13 Are lipids polar or nonpolar Do they dissolve easily in H2O nonpolar don t dissolve easily in water 14 What are two cellular functions of carbs Building blocks of nucleic acids cellulose etc 15 What is a buffer and how does it work It balances pH of solution by absorbing or releasing H s These notes represent a detailed interpretation of the professor s lecture GradeBuddy is best used as a supplement to your own notes not as a substitute 16 Four parts of amino acid Amine group carboxyl group R group 17 Are the hydrogen bonds between water molecules adhesion or cohesion Cohesion 18 Acids vs bases acids low pH proton donor bases high pH proton acceptor 19 Name 3 transport mechanisms across membranes Active passive co transport 20 Difference between saturated and unsaturated fats Saturated fats no double bonds unsaturated fats have double bonds 21 How does DNA and RNA differ DNA thymine deoxyribose RNA uracil ribose 22 What stage of cellular respiration is glucose converted to CO2 Krebs cycle actually the intermediate step 23 What are the inputs of the Calvin cycle NADPH ATP 24 What organelle contains DNA Nucleus also mitochondrion and chloroplasts 25 Explain two ways to produce ATP and which part of cellular respiration do they occur Substrate level phosphorylation Krebs cycle oxidative phosphorylation 26 Main purpose of fermentation in the cell Anaerobic respiration to produce NAD 27 Breaking apart protein into amino acids Exergonic reaction
