enzymes I think Flashcards
enzyme
acts as a catalyst in living organisms, regulating the rate at which chemical reactions without being altered
what is the suffix for enzyme
ase
2 positive feedback systems
childbirth and producing milk after labor
what hormones are involved in positive feedback
oxytosin
metabolism
combination of all the chemical reactions that are happening within the organism
enzymes are made of
proteins
where are the instructions to makes proteins
DNA nucleus rough endoplasmic reticulum
homeostasis
maintaining the internal environment of the body as equilibrium
active site
the portion of the enzyme that binds with he substrate
allosteric site
being a change in the shape and activity of a protein that results from combination with another substance at a point other than the chemically active site.
what 3 things cause a protein to denature
heat pH heavy metals
exocrine
glands secrete hormones into ducts
thyroxin
the main hormone secreted into the bloodstream by the thyroid gland.
metabolic rate
The amount of energy expended over a specific period of time
enzymes work on ____ substrate
1
components of the body which detect temperature changes
thermorecpetors
inhibitor function
occurs when the increase in the product of an enzyme catalyzed reaction cause it to slow by inhibiting th associated enzyme
diseases occurs if you don’t get enough
?
thyroxin function
which stimulates the metabolic rate. It controls the speed at which oxygen and food products react
if things are kept stead what kind of feedback is that
negative
what gland makes thyroxin
thyroid
what is attached to make more or less thyroxin
hypothalamus -> petuary gland
rxn that puts things together
dehydration synthesis
rxn that pulls apart
hydrolisis
induced fit
states that the binding of a substrate to an enzyme causes a change in the shape of the enzyme
hypothalamus
where thermo receptors are
lock and key
the model that considers the substrate and active site to be a perfect fir for each other
endocrine
glands secrete hormones directly into the blood
hyperthyroid
thyroid works over time causing loss of weight
hypo thyroid
doesn’t work enough gain weight
peptide
joins with receptor
period hormones
goes straight in
poisons
bind and reverse effects with receptors
