ETC=
|
push H+ out and will diffuse across inner mito membrane and atp will be made
Each carrier receives e from a donor and donates to the next carrier in the chain |
|
Chain 5 complexes-
complex 1 |
proton pump-gets e- from nadh and will push h+ out and gives e- to Co enzyme Q
net equation= NADH+Q+5H+@NAD +QH2 + 4H+ e-carriers=NADH to FMN to Fe/S to Q |
|
Chain 5 complexes-
Co enzyme Q details |
lipophilic with isoprene tail and carries e- from complex 1 to complex 3
can cary one or two e- |
|
Chain 5 complexes-
Complex 2 |
Not a H+ pump-
FAD picks up electrons here and will drop enzyeme on CoE Q FAD-Flavin di nucleotide can carry 1 or 2 e- Net Equation= FADH+Q@FAD+QH2 e-carriers=FADH to Fe/S cluster to Q Succinate Deydrongenase is complex 2 |
|
Chain 5 complexes-
Complex 3 |
Proton pump
Q gives e- from from 1 and 2 Net Equation = QH2 2 Cyto C ox+H+matrix@Q+2 Cyto Cred +4H+cytoplasm |
|
Chain 5 complexes-
Cytochrome C |
picks up e- from 3 and carries to 5- Cyto C is in inner membrane space
|
|
Chain 5 complexes-
Complex 4 |
drops 2 e- on osygen and get 2 h20 out
Net equation= 4Cyto Cred +O2+8 H+matrix@4cyto Cox.+ 2h20 +4H+cytoplasm e-carriers=Cua to heme a tp heme a3 to Cub |
|
picture of complex 3
|
reduced QH2 comes into dock site Q0 and drops off bothe e-,q oxidixed in q site gets 1 e- and leaves
Qh2 (another one) drops off e-s , Cyto C leaves with e-,a nd now fully reduced Q leaves |
|
Complex 5
ATP synthase Structure |
2 parts F0 and F1
F0=a,b,c, units F1=greek letters alpha, beta, gamma, delta, epsilon 3 pairs of alpha beta held in place by gamma |
|
1.)C subunit or C ring
2.)A unit |
1.)10 units with aspartic acid residue
2=2 half channels |
|
Mechanism of rotation
|
1/2 channels fill with h+ and protonate the aspartic acid residue, residue no longer charged, can drop off h+ on other side after 10H+ bound
|
|
F1 cycle
|
3 alpha beta dimers interface with gamma subunit and can form:
O=open, ATP and ADP pi diffuse in and out L=ADP + Pi in and nothing else happend T= ADP Pi are force together to form ATP T |
|
Net yields-
1=Glycolysis 2=TCA O3=Oxidative Phosphorylation |
1=2 ATP 2 NADH
2=2 ATP 3=30 ATP, 2.5 ATP per NADH |
|
ATP/ADP Translocase
|
Need to get ADP into matrix from cytoplasm to be used by ATPsiynthase- ADP cytosolic binds, conform. change ADP in and ATP out
|
|
How does glycerol get intot he glycolytic pathway?
|
Glycerol Kinase turns glycerol into glycerol phosphate
Glycerol phosphate dehydrogenase turns Gly pi into dihydroxyacetone (UDAP) |
