[Electron-transport] one more addition

[Jennifer Deegan (nee Clark)]

Hi,

Thank you for your comments. Clearly that was not the way to go, so I 
will go back a few steps and explain the problem that I am trying to 
solve, and maybe you will have better ideas.

I need to find an is_a path to the root (by tomorrow lunchtime GMT) for 
the following terms:

photosynthetic electron transport in cytochrome b6/f ; GO:0009775
(undefined)

photosynthetic electron transport in photosystem I ; GO:0009773
def: Electrons move from the primary electron acceptor (Quinone, X) 
through a chain of electron transport molecules in the thylakoid 
membrane until they reach ferredoxin which passes the electron to the 
ultimate electron acceptor; NADP.

photosynthetic electron transport in photosystem II ; GO:0009772
def: Electrons move from the primary electron acceptor (Quinone, Q) 
through a chain of electron transport molecules in the thylakoid 
membrane until they reach the ultimate electron acceptor of Photosystem 
II, which is plastocyanin (PC). The electron is then passed to the P700 
chlorophyll a molecules of the reaction centre of photosystem I.

photosynthetic electron transport in plastocyanin ; GO:0009776
(undefined)

photosynthetic electron transport in plastoquinone ; GO:0009774
(undefined)

Does anybody have any good ideas for how I could do that? I just need to 
make an is_a relationship from the terms up to another term that has a 
direct is_a path up to the term 'biological_process'.

I am working in the file go/scratch/electron_transport.obo

Thanks,
