Monosaccharide formula correct answer: (CH2O)n (n is 3 or more) Aldotriose correct answer: Also known as glyceraldehyde, simplest aldehyde monosaccharide (n = 3), has L and D isomer (centre carbon is chiral) Ketotriose correct answer: Also known as dihydroxyacetone, simplest ketone monosaccharide (n = 3), non chiral Carbon numbering correct answer: Aldoses always have aldehyde and C1, ketoses have ketone at C2 Sugar naming correct answer: triose, tetrose, pentose, hexose, etc., ...

BCH210 Final Exam Questions with complete solution 2023

Classifications of proteins are based on.... correct answer: - position in the cell (membrane/soluble/extracellular) - function (transporter/enzyme/structural/hormone) - other molecules associated w/ it (glycoprotein - sugar, lipoprotein - lipid) A salt bridge is an....bond and is an example of a.....interaction correct answer: ionic, non-covalent Are salt bridges easier to break in biochem? Why? correct answer: - Yes- Interacting w/ surrounding solvent (water) Is an O bonded to a ...

BCH210 FINAL QUESTIONS WITH COMPLETE SOLUTIONS UDP glucose pyrophosphorylase - Answer--transfers a UMP onto G1P on the non-reducing ends to form UDP-glucose -requires a UTP -2 phosphates is the leaving group phosphoglycomutase - Answer--isomerase glucose 1,6 biphosphate converted into G1P which could then be added onto the glycogen during glycogen synthase. -has a phosphate in its active site, and donates the phosphate to C1 and accepts the phosphate on C6 mitochondria structure - An...

BCH210 RUNBACK EXAM QUESTIONS WITH ANSWERS GRADED A+ Lactate dehydrogenase - Answer-Pyruvate + NADH --> lactate + NAD+ Regenerates NAD+ for glycolysis when O2 is unavailable; in red blood cells, lactate is always produced since no mitochondria Cori cycle - Answer-1. Lactate is produced in the bloodstream by red blood cells 2. Liver picks up lactate; lactate dehydrogenase converts it back into pyruvate 3. Pyruvate is converted into oxaloacetate, where it either enters the CAC or GNG...

BCH210 CLASS 6 EXAM QUESTIONS AND ANSWERS ALL CORRECT The...on N gives peptide a.......bond character due to....., preventing....of the peptide bond - Answer-- lone pair of e - partial double - resonance - rotation Peptide bonds are....but...... The first feature contributes to the peptide bond by allowing......., through the....... - Answer-- polar - uncharged - resonance - breaking of the C=O bond The plane of the peptide bond is always in the....... - Answer-same organizat...

Functions of biological membranes correct answer: - barrier (import/export) -compartmentalization of essential molecules (incrs. efficiency) - cell signaling-mediated by pr & lipids (receptors) - modulate cell-cell recognition (glycoproteins & glycolipids) What's responsible for membrane formation correct answer: decrease in ionic interactions w/ h2o (HYDROPHOBIC EFFECT) -h20X tails aggregate to hide from h2o (lots of n-c interactions) -polar heads interact w/ h2o Decreases membrane ...

functions of the membrane correct answer: -the structure of the membrane is key for its function -act as a barrier regulating import and export of molecules -help with compartmentalization of the cell, creating particular environments for certain processes so multiple specialized processes could occur at once -modulates cell-cell recognition with their glycoproteins and glycolipids located on the outer leaflet facing the cytosol -signaling across the membrane by proteins and lipids p...

identify all the polar amino acids correct answer: cysteine (cys), asparatate (asp), glutamate (glu), histidine (his) , lysine (lys), asparagine (asn), arginine (arg), serine (ser), threonine (thr), and glutamine (gln) identify all the nonpolar (hydrophobic) amino acids correct answer: alanine (ala), proline (pro), phenylalanine (phe), valine (val), leucine (leu), and isoleucine (ile) identify all of the amphipathic/mixed properties amino acids: correct answer: methionine (met), tyrosin...

sucrose correct answer: glucose + fructose with a glycosidic bond simple monosaccharide correct answer: formula: (CH2O)n -simplest carbohydrates -have an aldehyde or ketone group sugars with a aldehyde have a prefix aldo- sugars with a ketone group have a prefix keto- -if a ketose, the ketone group is always at carbon 2- this decreases the amount of isomers that could form -made up of chiral carbons- allowing the sugars to form different isomers, leading to structural diversity (aldos...
