for every aminoacid introduced into a protein you need 2ATP and 2GTP;i don't know for what is the second ATP if the first one is for activation of aa.
anyone has a idea?

in activation of AA it is two phosphate bonds r used from one ATP.....its not 2 ATP.....and one phosphate from a GTP for binding to A site
and one phosphate from another GTP for translocation.......
so totally its 4 phosphate high energy bonds used

why do you use 2 phosphate bonds from ATP?
aa +ATP :arrow: aa-AMP + PP
sorry if it's a silly q but i don't understand.

the 2 high energy bond is used in the covalent attachment of t-RNA with the aminoacid......with the help of enzyme aminoacyl t-RNA synthetase
