can galactose be convert into fructose?

... by fructokinase, from where it enters the glycolysis pathway, which can then generate glucose by running in reverse. Of yeah and the stuff about transporters has nothing to do with the metabolism part. As for the first question, I can only guess that it is a more favorable reaction to phosphorylate ...

membrane permeability - let's make it clear!

... of biological membranes, I would like to see clearly now. What substances can FREELY travel through biological membranes (with NO help of transporters, whatsoever)? It is also not clear whether all biological membranes act the same way in point of permeability (prokaryotic vs. eukaryotic; ...

glucose absorption

... where this particular transporter is expressed. As for your second question: I don't exactly what the kinetics of these particular two types of transporters are, but generally secondary active transport proteins(like the glucose/Na symporter) work about as fast as ping-pong uniporters(like the ...
