Intro to Biochemistry Flashcards
biological chemistry
BIOCHEMISTRY
molecular basis of life
BIOCHEMISTRY
living organisms, deals with biomolecules and biochemical reactions
BIOCHEMISTRY
single organic compounds
atoms > elements > monomers
primary substances
polymers/monomers > supramolecular structure
organelles
cells > tissues > organs > organ system > organelles
Swedish founder, composition of matter, mid 1700
Carl Scheele
biochemicals produced by living organisms, urea by heating ammonium cyanate, 1828
Friedrich Wohler
cell theory, 1840
Schleiden & Schwann
states that “every living organism have a small factory called cells, to function.”
Cell theory
chromosomes in 1875
Walther Flemming
German scientist who
coined the word “biochemistry”
Carl Newberg
fermentation of sugar, 1897
Edward & Hans Buchner
glycolytic pathway, 1925
Embden & Meyerhof
breakdown of carbohydrates and
sugars, specifically glucose
Glycolytic pathway
produces energy and other substances
Metabolism
Proposed the Kreb cycle, 1937
Hans Krebs
produces a lot of energy molecules in
ATP
tricarboxylic acid cycle
DNA as information molecules, 1944
Avery, McLeod & McCarty
double helical structure of
DNA, 1953
James Watson & Francis Crick
central dogma of biology
Francis Crick
“rotary engine” that generated ATP in 1997
Paul Boyer & J. Walker
powerhouses of the cell
Mitochondria
“pump” that drives sodium and potassium
across membranes
Jens Christian Skou
osmotic balance
“proton pump” or the “sodium-potassium”
“mad cow disease”; prions
Stanley Prusiner
abnormal proteins that exist in the CNS of
the cow
prions
electron microscope; he wanted to know the structure of prion molecules
Ruska, et.al.
3 principles areas of chem
structural chemistry
metabolism
chemistry of molecular genetics
