mitochondrial structure
DESCRIPTION
Mitochondrial structure. Two compartments inner and outer Inner= MATRIX Lotsa folds=…why? Outer= acid…why?. The Mitochondria. Double membrane Has it’s own DNA!! Can reproduce in cell…! Endosymbiont?? Possible evolution?. The Fate of PYRUVATE. Taken into mitochondria - PowerPoint PPT PresentationTRANSCRIPT
Mitochondrial structure Two
compartments inner and outer
Inner=MATRIX Lotsa folds=…
why?
Outer=acid…why?
The Mitochondria Double
membrane Has it’s own
DNA!! Can reproduce in
cell…! Endosymbiont?? Possible
evolution?
The Fate of PYRUVATE Taken into mitochondria Broken down to ACETATE CO2 produced
Binds to large protein Coenzyme A to produce acetyl Coenzyme A
The TCA or KREBS CYCLE
CO2 NADH & FADH
2 more ATP
Alternative pathway… Mitochondria and O2 needed Uses NADH and
FADH produced in previous reactions
To make more ATP
Lots more!!
What is NADH?? FADH?? ENERGY CARRIER! Same for FADH Carrier to…?
Electron Transport System ETS (cytochrome
chain) is a series of reduction/oxidation reactions
Enzymes embedded in mitochondrial membranes
ETS RedOx reactions
pump H+ out of matrix to the outer compartment
H+ = acid…aha!
Summation of Reactions H+ can only “fall” back into matrix
thru A special enzyme/protein complex ATP SYNTHASE…guess what that
makes?? But…how much ATP??
