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
