Metabolism Flashcards
metabolism
chemical reaction occurring in cell for living, growing and dividing
anabolism
production of new cell component, process requires energy (making of amino acids or proteins)
catabolism
obtain energy and reduce power from nutrients (cellular respiration)
endergonic
less complex, anabolic
exergonic
complex, catabolic
carbohydrates / some amino acids / glycerol
glycolysis
fatty acids / some amino acids
pyruvate oxidation
some amino acids
citric acid cycle
degradation biological macro-molecules
glycolysis ~> pyruvate oxidation ~> citric acid cycle ~> oxydative phosphorilation
homeostasis
steady state, thermoregulation
ectotherm
behavioral regulation
endotherm
internal regulation
melatonine
makes you sleep
body temperature decrease
paracrine signalling
cell gives close signal to an other cell
synaptic signalling
signals produced bu the synapse of nerve system
plant hormone
long distance signalling via vascular or secreted to environment
animal hormone
long distance signalling via endocrine system
cell signalling : reception
signalling molecule binds to a receptor protein, causing it to change shape
cell signalling : transduction
3 relay molecules in a signal transduction pathway
cell signalling : response
activation of cellular response, activation of glycogen phosphorylose
plasmodesma
channel between plant cell walls
tight junctions
join adjacent in animal cells
desmosones join
2 animal cell together
gap junction
channel between animal cells
