--- End quote ---
oxygen acts as the final electron acceptor in the ETC - its necessary cuz it being can combine with the electron which has passed through th ETC and it accepts it (i guess otherwise it wod have no wer else 2 go this lone electron) so wat u need 2 no is without a final electron acceptor those energy changes down ur ETC wont work... there are a few markin scheme answers about this - get 2 no them...
By the way good job attachin ur doubts - saves alot of trouble from jus naming them
and ill answer the specimen 5 questions after monday (cuz i hav an xam n i havent done th ppr) hope thts ok!
cya on wednesday ;)

It's alright! I'll call you up on Monday (insha Allah) if I have any doubts remaining- hopefully not!
Thank you once again for your help and time!
*I could hug you right now* :D
All the best for Chem! ;)

Using a respirometer for finding effect of temperature for rate of respiration. Do we use soda lime (KOH) in the apparatus?
$H00t!N& $t@r:
question!
-Some people have a rare disease caused by a single change in the DNA nucleotide
sequence of the gene coding for lysozyme. The change leads to the formation of an
insoluble protein that has a different structure to the normal soluble lysozyme molecule.
Suggest how a change in the gene can lead to the differences observed between the
normal lysozyme and the changed lysozyme.
