\.5 core concepts - Answer--information flow
-structure function
-energy transformation
-evolution
-systems
\.5' vs 3' - Answer-- 5' will have an OH or phosphate group bound to C-5' of the sugar
- 3' will have an OH bound to C-3' of the sugar
\.acidic/basic - Answer-acidic: low pH
basic: high pH
\.activation energy - Answer-Energy needed to get a reaction started
\.active site - Answer-a region on an enzyme that binds to a protein or other substance during a
reaction.
\.affinity - Answer-attraction between two biological molecules, to bind, modify, or destroy
\.allele - Answer-one of a number of different forms of a gene on the same place on the
chromosome
\.amino acid - Answer-Building blocks of prote
, \.aminoacyl tRNA synthetase - Answer-During protein synthesis, an enzyme that attaches the
correct amino acid to a tRNA molecule to form a "charged" aminoacyl-tRNA.
\.ATP - Answer-(adenosine triphosphate) main energy source that cells use for most of their
work
\.catalyze - Answer-to lower activation energy
\.codon/anti-codon - Answer-A codon is a three-base sequence (three nitrogen bases in a row)
on mRNA. It calls for a specific amino acid to be brought to the growing polypeptide. An
anticodon is a three-base sequence on tRNA. It matches the codon.
\.Compare and contrast different types of enzyme regulation - Answer-competitive inhibition:
inhibitor binds to active site blocking the active site from the substrate
allosteric regulation: a regulatory either has to be present or cannot be present in order for the
active site to be the right shape to accept substrates
\.coupled reaction - Answer-a chemical reaction in which an exergonic reaction powers an
endergonic reaction
\.coupled reactions - Answer-pairs of chemical reactions in which some of the energy released
from the breakdown of one compound is used to create a bond in the formation of another
compound
ex. ATP
\.DNA - Answer-A complex molecule containing the genetic information that makes up the
chromosomes.
