Matching Flashcards
(40 cards)
Acetylcholine
neurotransmitter, activates muscle, PNS and CNS, opens Na+ channels
Aldosterone
causes the seminiferous tubules to produce inhibin
ATP synthase
enzyme, free energy of the electrochemical gradient is reduced, synthesis of ATP to ADP, 4 H+ to produce 1 ATP, creates ATP from ADP + P
Beta pleated sheet
an example of a secondary structure
Bond energy
measure of the stability of a chemical bond
Calcitonin
controls level of calcium in blood
Chemiosmosis
a process for synthesizing ATP using the energy of an electrochemical gradient and the ATP synthase enzyme
Condensation reaction
results in the formation of water
Dendrites
short, branching terminals that receive impulses and relay the impulses to the cell body
DNA polymerase I
proofread by excising incorrectly paired nucleotides, removes RNA primers and replaces them with the appropriate deoxyribosenucleotides during DNA replication
DNA polymerase III
responsible for building new DNA strands during replication, enzyme responsible for synthesizing complementary strands of DNA during DNA replication, 5’ to 3’ direction
Entropy
randomness or disorder in a collection of objects or energy
Free energy
energy that can do useful work
Glial cells
support neurons by nourishing them, removing wastes, defending against infection, function as structural support cells
Gyrase
the bacterial enzyme that relives tension produced by the unwinding of DNA during replication
Helicase
unwinds DNA
Hydrolysis reaction
requires water to proceed
Insulin
increases uptake of glucose from the blood - decrease in blood sugar
Isomerization
one molecule is formed into another, same chemical formula but different arrangement of atoms
Lactate fermentation
pyruvate gets converted into lactic acid
Lagging strand
new DNA strand synthesized in fragments
Leading strand
new DNA strand that is synthesized continuously
Ligase
links sugars and phosphates together
Light reactions
use light to generate ATP and NADPH2, Calvin cycle
