|
function of glycolysis
|
oxidation of glucose to 2 pyruvate and 2 atp
|
|
|
pyruvate to acetly coA
|
enters krebs cycle
|
|
|
kreb's cycle
|
acetly coA is combined with oxaloacetate to produce citrate and then is cycles back to ozaloacetate as redox rxn produce nadh and fadh2
|
|
|
Function of ETP and chemiosmosis
|
NADH and FADH2 transfer electons to carrier molecules in mitochondrial membrane. H+ is pumped into intermembrane space and electrons are delivered to .5O2.
|
|
|
function of fermentation
|
anaerobic catabolism
|
|
|
anaerobic catabolism
|
glycosis follwed by regeneration of NAD+ so glycolysis can continue. Pyruvate is either reduced to ethyl alcohol and CO or to lactate
|
|
|
Oxidative phosphorylation uses a process called
|
chemiosmosis
|
|
|
chemiosmosis couples
|
proton gradient called porton motive force...which drives H+ back through ATP synthase to produce ATP
|
|
|
proton gradient is formed when
proton gradient to synthesis of ATP |
h+ pumped from matric intro intermembrane space
|
|
|
ATP using engery from
|
redox rxn as electrons pass thru etp
|
|
|
in the conversion of glucose and oxygen tocarbon dioxide and water, which moelcule is reduced? which moleucle is oxidized?
|
oxygen(added electrons)
glucose (electrons taken away) |
|
|
what happens to entery that is released in this redox rxn?
|
stored in ATP or used as heat
|
|
|
NAD+ is called an
|
electron acceptor or oxidizing agent
|
|
|
NAD+ reduced form is
|
NADH
|
|
|
glycolysis breaks glucose into
|
2 molecules of pyruvate
|
|
|
substrate level phsphorylation
|
an enzyme transfers a phosphate group from substrate to ADP
|
|
|
WHEN ELECTRONS move closed to a more electroneg. atom...
|
energy is released
|
|
|
in the rxn C6H1206+6O2=602+6H2O
|
OXYGEN becomes reduced
|
|
|
a substrate that is phophorylated
|
has an increased reactivity; it is primed to do work
|
|
|
oxidative phosphorylation...
|
produces 2 ATP per every NADH it oxidizes
it involves the redox rxn of the ETP IT INVOLVES an ATP synthase located in the inner mitochondieal membrane it depends on chemiosmosis |
|
|
substrate level phospoylation
|
is the enery souce for facultative anarobics under anarobic conditions
|
|
|
photosynthesis converts
|
light energy into chemical enery which is stored in orgnaic molecules
|
|
|
photosynthese involves
|
calvin cycle and light rxn
|
|
|
cavin cycle
|
is when the CO2 is fixed with RuBP which is reduced to form G3P which is made into carbs
|
