Bio 205 WWU exam 1
disulfide bond - ✔️✔️formation of covalent bonds between particular amino acid side
chains that affects protein tertiary structure
allosteric regulation (activation) - ✔️✔️active site becomes available to substrates
when a regulatory molecule binds to a different site on the enzyme
central dogma - ✔️✔️DNA is transcribed into RNA which is translated into proteins
endothermic - ✔️✔️thermal energy is absorbed by the system during the process (ex:
state change from liquid to gas H2O)
exothermic - ✔️✔️releases thermal energy to the environment (ex: water vapor to liquid
water)
oxidation - ✔️✔️loss of electrons
reduction - ✔️✔️gain of electrons
catalysis - ✔️✔️speed up chemical reactions
covalent bond - ✔️✔️in primary structures of proteins. strongest types of bonds.
sharing of electrons
gram positive - ✔️✔️prokaryotes. cells take up dye, peptidoglycan cell wall, no outer
membrane
gram negative - ✔️✔️prokaryotes. cells don't take up dye, have an outer membrane
phospholipid bilayer - ✔️✔️hydrophobic tails, hydrophilic heads, has pores in protein
channels for molecules to move through. small nonpolar can get through
ionic bonds - ✔️✔️not as strong as covalent bonds in water because water can interact
w charged ions due to its polar nature
solute - ✔️✔️dissolved substance
solvent - ✔️✔️the liquid that does the dissolving (usually water)
ionic substances - ✔️✔️dissolve because water molecules are attracted to the positive
and negative charge of each ion
, polar substances - ✔️✔️dissolve because their molecules form hydrogen bonds with
the surrounding water molecules
acids - ✔️✔️substances that release protons (H+) when they dissolve. can be strong or
weak depending on how readily they give up their protons
pH - ✔️✔️measure of the amount of hydrogen ions (H+) in a solution
sugars - ✔️✔️can exist in D and L forms based on isomerization. have free OH-
groups, can form polysaccharide chains
fatty acids - ✔️✔️behave like acids. almost all attach to other molecule by the carboxyl
group. amphipathic. hydrocarbon chains
amphipathic - ✔️✔️contains both hydrophilic and hydrophobic regions
amino acids - ✔️✔️have a carboxyl and amino group, so they are simultaneously acids
and bases. determine shape and function of proteins
peptide bonds - ✔️✔️resonance in these bonds gives two bonds partial double bond
character
primary structure - ✔️✔️covalent bonds are involved in the creation of these. unique
sequence of amino acids in a polypeptide chain determined by its coding DNA
sequence
secondary structure - ✔️✔️hydrogen bonds primarily stabilize. side chains don't
participate in this
noncovalent bonds - ✔️✔️involved in folding polypeptide chains into 3D proteins
(secondary, tertiary, quaternary)
beta sheet - ✔️✔️type of secondary structure. can be parallel or anti parallel
alpha helix - ✔️✔️type of secondary structure that look like coils
