In class we watched a demonstration where the color of the solution oscillated between orange and blue. This is a very complicated reaction with multiple pathways the reaction can take. One pathway can be described as follows: H2O2 + 3 I- + 2 H+ → I3- + 2 H2O Step 1. H2O2 + H+ → H3O2+ Step 2. H3O2+ + I- → H2O + HOI Step 3. HOI + I- → OH- + I2 Step 4. OH- + H+ → H2O Step 5. I2 + I- → I3- How many of the following statements are correct based on the information given? Select ...

Alcohol - Ketone - Amine - Ether - Amide - Ester - functional groups - Alkyl - An alkane missing a hydrogen Aromatic compound - Cyclic, planar, with every atom of the aromatic ring having a p orbital, while obeying hackles rule of 4n+2 pi electrons Vinyl - Hydrolysis Reaction - Carboxylic Acid - pKa ~ 5 Enantiomers - stereoisomers that are non super imposable mirror images Diastereomers - - Same molecular formula, same bond connections, NOT mirrors...

BIO 441A EXAM 3 STUDY GUIDE WITH COMPLETE SOLUTION. LECTURE ONE - METABOLISM INTRODUCTION ● Autotrophs synthesize all their own cellular constituents from simple molecules ● Heterotrophs obtain energy through oxidation of organic compounds and therefore rely on autotrophs ● Metabolism involves many reactions such as ○ Glycolysis/gluconeogenesis ○ The citric acid cycle ○ Oxidative phosphorylation ● Catabolism is the degradation of biomolecules ○ Energy rich nutrients are...
