rRNA translates mRNA into proteins not tRNA so its not a

somy · Answer

good that you know this much :D 
the question has a trick 
it uses 'ribosome' to confuse you 
what the question is originally asking 
is what is the function of enzyme? what does enzyme do to the reaction?

somy · Answer

thats the original question 
and ribosome is used as one of the examples of type of enzymes 
since we have peptide enzymes and ribosomal enzymes

anonymous · Answer

It is also, in a very indirect way, to also get the fact that not all enzymes are proteins out there.  The vast majority of enzymes are proteins.

yep yep @mrdoldum very nice but hell-like lol, been through thousands of these indirect brain killing questions (this one's fine tho) +_+
