-
-
enazymes lower
activation energy
-
bacterial catabolism
include breakdown of glucose to release atp
-
metabolism produces NADH, FADH, ATP
- 10 NADH-30ATP
- 2 FADH-4atp
- 4 ATP-4 atp
38 total atp
-
glycoysis requires
no oxygen
-
glucolysis pathway
- glucose
- glu-6-p - ADP
- fruc-6-p
- fruc-1,6-dip- ADP
- gly-3-p
- 3 pga- NADH2
- 1,3- pga
- 3 pga- 2atp
- 2 pga
- pep
- pyruvate- 2atp
-
krebs cycle requires
oxygen
-
krebs cycle
- pyruvate
- acetyl- coA - NADH2
- coA+ oxalocetate
- citrate
- ketoglutarate- NADH2 -co2
- succinyl-CoA
- succinate- FADH2
- fumarate
- malate
- oxalocate- NADH2
-
anaerobic fermentation
- pyruvate to
- lactate, ethanol, co2 propinoate
-
enzyme temp
temp increase would destroy cellular protien so must speed up reaction at compatible temps
-
apoenzyme
protien part- inactive
-
holoenzyme
apoenzyme + cofactor
-
cofactor
ions of zinc NAD mag and calcium
-
conenzyme
cofacter must be an organic molecule
-
enzyme mechanism
- substrate + active site= enzyme substrate complex
- subtrate transformed into products then released
- enzyme unchanged
-
-
non competitive inhibitors bind at
- allosteric sight so the activation site changes shape - nonfunctional
- activity then reduced
-
competitve inhibitors
bind in the active site so substrate cannot
-
ATP
- high energy bonds
- energy currency
- unstopable bonds
-
-
-
substrate phos
atp generated fro direct transer
-
glucose most comnon
carb energy source used by a cell
-
-
fermentation
- glycolusis
- lactic acid
- alchol
- co2
-
anaerobic respiration
final electron acceptor is inorganic molecule
-
aeorbic respiration
final electron acceptor is 02
