BIOC 3621: Test 1
The synthesis of urea from ammonium cyanate... *** helped dispel the vital force theory
Vital Force Theory *** disproved by Friedrich Wohler
organic compounds are only formed in living cells
What makes up proteins *** Amino Acids
What makes up nucletides *** Nucleic Acids
What is the longest macromolecule *** DNA
What are the 3 domains *** Bacteria (PROKARYOTIC)
Archae (PROKARYOTIC)
Eukarya
What is the difference between prkaryotes and eukaryotes *** the existence of a well defined nucleus
What does electronegativity produce *** polar bonds
What dissolves in water *** ionic compounds and low MW polar compounds
-because of electrostatic attraction of unlike charges
-their ion-dipole (ions) and dipole-dipole interactions (ethanol or acetone)
, Van der Waals *** interaction between non polar molecules = weak
Micelle *** can be used as a detergent
-polar hydrophilic head
Hydrogen Bonds *** H with F, O, N
-interaction between dipoles
-non covalent
How many H bonds can water have *** 4 because of the tetrahedral arrangement
-2 donor and 2 acceptors
What were the original gases present in Earth's atmosphere *** NH3, H2S, CO, CO2, CH4, N2, H2, H2O
RNA *** catalyzes it's own processing
-the original coding material
double origin theory *** development of catalysis and coding system came separately
-combination of the two produced current life
Prokaryotes *** single celled, have RIBOSOMES
Glyoxysomes *** only in PLANT cells, catalyzes glyoxylate cycle
