"Vitamin B" solution to level 17
cbmi...@gwise.louisville.edu
I just discovered this game this weekend (via Stumble!), and went nuts
over it. It is great!
I got up to level 17. Here's my solution to 17, which I call the
"Vitamin B" solution. The B1 inside the membrane is used to signal
"inside", and the B0's are used to signal "outside", in order to help
the E's out and the F's in. I guess the B's act as a catalyst for
these reactions?
Actually, the Ax membrane does not stay intact, but the transport does
not open the contents of the membrane. This solution would not survive
a caustic agent. Does my solution model anything that happens in
nature?
Here it is, Vitamin B:
//transport of E's to exterior
e1 + a3 => e5a23
e5 + a4 => e6a24
a23a24 => a25 + a26
e6 + b1 => e7b2
b2 + a26 => b3a28
b3 + a25 => b4a27
e7b4 => e8 + b5
a28 + a27 => a38a37
a37e8 => a47 + e9
a38e9 => a48 + e0
a48b5 => a4 + b6
a47b6 => a3 + b1
//transport of F's to interior
f0 + a3 => f5a17
f5 + a4 => f7a18
a17a18 => a17 + a18
b0 + f7 => b2f8
b2 + a18 => b3a30
b3 + a17 => b4a31
b4f8 => b5 + f9
a30 + a31 => a32a33
a32b5 => a4 + b6
a4f9 => a4 + f10
a33f10 => a35 + f1
a35b6 => a3 + b0
Take care!

Thanks for writing. Your solution works nicely. I think the reactions
you use could be slightly simplified but it is a good idea to use
inside and outside things to direct the transport.
As to whether these solutions model anything seen in nature - I'm not
sure. Membrane transport in cells often just uses tubes to control the
flow of small molecules across the membrane:

As far as I know, if a molecules becomes actually embedded in a
membrane it is more-or-less stuck there, unlike in OB where we can
carefully extract it again.
