chapter 1 Flashcards
What is biochemistry?
structures, mechanisms,
and chemical processes
that are shared by all
organisms and provides
organizing principles that
underlie life in all its
diverse forms….the
molecular logic of life
How did biomolecules arise?
The earliest atmosphere consisted of small compounds like H2O, N2, CO2, H2S, CH4 and NH2. UV light from the sun or lighting provided the energy to create simple organic compounds and the basic
functional groups
What is included in prebiotic soup?
nucleotides from components of Earth’s primitive atmosphere
Biomolecule synthesis sheet
What is the self-replicating system evolved from simple molecules?
what does specific base-pairing between complementary functional groups permit?
one member of a pair to determine the identify and orientation of the other member
What does complementarity make possible?
for a macromolecule to replicate, or copy itself, by directing the assembly of a new molecule from smaller complementary
