Types of phosphorylation ?

Post by missim » Sun Oct 04, 2009 1:54 pm

Can you explain substrate level phosphorylation, photophosphorylatin, oxidative phosphorylation, chemosynthetic phosphorylation???????? Please :cry: :cry: :cry: :cry:

I see, you like my link :-D :-P

Cis or trans? That's what matters.

I am really only certain about the substrate level phosphorylation and the oxidative phosphorylation. Substrate Level phosphorlation takes place in the Cell Cytoplasm. Oxidative Phos is when Hydrogen ions are pumped from the INTRAMEMBRANE of the Mirochondria into the Michondrial Matrix. Hydrogen ions go two at a time through an enzyme known as ATP Synthase. The process of 2 Hydrogen ions going through the ATP Synthase into the Mitochondrial Matrix is called Oxidative Phosphorlation.

They definityvelly don't go by 2, they are always one by one (althrough they do not pass directly, instead thez do a round with the ATPase stationary part and then go out)
http://en.wikipedia.org/wiki/Photophosphorylation Photop. takes place in chloroplasts during photosynthesis, surprisingly.
Chemosynthetic phosphorylation is apparently phosphorylation due to utilize of some unusuall chemicals as hydrogen etc.

Substrate level phosphorylation takes place inside the mitochondria during glycolosis and the Krebs cycle.
Oxidative phosphorylation takes place in the membranes of the mitochondria during the electron transport chain.
Photo phosphorylation takes place in the chloroplasts of plants
and I'm pretty sure chemosynthetic phosphorylation (may be called something else) is like oxidative phosphorylation, except not involving oxygen, for example in anaerobic bacteria and other chemoheterotrophic organisms.
They are all involved in making ATP
