Metabolism Flashcards
what is metabolism
sum of all reactions
breaking bonds
what is catabolism
energy releasing reactions
exergonic
breaking down
what is a hydrolytic reaction
chemical bonds being broekn
what is anabolism
energy consuming reacions
endergonic
building
is dehydration synthesis anabolic or catabolic
anabolic
what are enzymes made of
protein
what do enzymes act on
substrates
what do enzymes do to activation energy
lower it
what is a cofactor
vitamin or mineral
non protien factor
what is the michaelis-menton equation
E+S=ES=E+P
what is competitive inhibition
compete with active sitwe
who gets there first
what is non-competitive inhibition
allosteric site-change configuration
what is an allosteric site
not an active site
does not fit perfectly
what are REDOX reactions
primary reactions of metabolism
reduction anf oxidation
what does OIL RIG stand for
oxidation is lost (electron)
reduction is gained (electron)
what do cellular respiration and fermentation start with
glycolysis
what do you put in for glycolysis
glucose
what do you get out for glycolysis
2 ATP
2 NADH
2 pyruvates
what do you put in for the krebs cycle
2 pyruvate
what do you get out for the krebs cycle
2 ATP
8 NADH
2 FADH
Co2
what is the net ATP for prok cells undergoing energy metabolism
38
what is the net ATP for euk cells undergoing energy metabolism
36
what is the electron transsport chain
series of carrier molecules capable of redox reactions
release of energy as elecrtons pass through series of carrier molecules
chemiosmosis
what is chemiosmosis
protons pumped across membrane
what is anaerobic fermentation
recycles NAD
glucose broken down to pyruvic acid via glycolysis
organic molecules become final electron acceptor
