i thinks it does what it does then nor epinephrine cancels it ...georgia ..daises?
that poster is badasserery ...thanks dude so much
It gets reabsorbed back into the neuron and broken down by COMT and MAO back into inactive metabolites.
Dude, that is one heck of a poster. I've studied a lot of that but never seen it all together. How can I get my hands on one of those?
One thing to remember about
that poster, that is what is supposed to happen under optimal conditions. We don't have optimal conditions. Each of the reactions on that chart are pH and substrate dependent. There are also physical limitations we must overcome. It doesn't do you any good if your substrate that catalyzes a reaction isn't located where it is supposed to be. An example, if your cobalamin is outside the cell, it can't react with homocysteine to produce methionine inside the cell. It must be able to enter the cell.
I can see so many reactions that require magnesium or zinc for them to occur. So if I were trying to slow down or stop this cycle, I'd reduce the concentration of these substrates. But we have a lot more issues than just that. We have entire molecules that aren't there. Robbing Peter to pay Paul has its consequences.
