Similarities
- involve transport of electrons
- ETC in membrane
- energy release used to pump, protons, to create a gradient
- protos diffuse down gradient, across membrane, down a stalked particle with ATP synthetase
|
Differences
- chloplasts have no substrate level phosphorylation
- in chloroplast ETC electrosn come from water
- in mitochondria electrons come from respiration/hydrogen carriers
- in mitochondria, hydrogen from glucose/fats/amino acids
- in mitochondroia- oxygen is final electron acceptor
- in cholorpats, ETC is part of cyclic photophosphorylation
- In mitochondria, H+ in inter membranal space
- in chlorplasts the high H+ is in the thylakoid cavity
- mitochondria have three types of proton pump
- chloroplast ahve 1 type of proton pump
