Chapter 5 Flashcards
Metabolism
Metabolism is the collection of what
of controlled biochemical reactions in an organism
metabolisms ultimate function is what
to reproduce the organism
what does metabolism consist of
catabolism and anabolism
catabolism def
breaking down
anabolism def
building up
metabolic processes #1
every cell acquires nutriets
metabolic processes #2
metabolism requires energy from light or catabolism of nutrients
metabolic processes #3
evergy is stored in adenosine triphosphate (ATP)
metabolic processes #4
cells catabolize nutrients to form precursor metabolites
metabolic processes #5
precursor metabolites, energy from ATP, and enzymes are used in anabolic reactions
metabolic processes #6
enzymes plus ATP form macromolecules
metabolic processes #7
cells grow by assembling macromolecules
metabolic processes #8
cells reproduce once they have doubled in size
Catabolic pathways info
like making money. Large to small. exergonic. store energy as ATP
REDOX is what
oxidation and reduction. so the shuffling of electrons to make ATP or do processes
what are the 3 important electron shufflers
(NAD+)
(NADP+)
(FAD)
what is the goal of regulating metabolic function
to limit wasting energy, and to maximize efficiency
when are enzymes synthesizes
only when substrate is available
what does metablic function prioritize
energy efficeinet molecules
Enzymes do what
speed up the rate of chemical reactions
what kinds of factors influence the rate of enzymatic reactions
temp
pH
enzyme concentrations
substrate concentration
presence of inhibiors
carbohydrate catabolism is reduce or oxidize
oxideized
carbohydrates def
common energy source for anabolismw
