Hello! I know that certain enzymes in living organisms "prefer" C12 because of its lighter mass.  Using this 
logic, I dexided that when an organism dies, more C13 is left over since the body reacts with C12 faster.  

However, my tutor said otherwise (with uncertainty) and my teacher just re-explained that c12 reacts 
quicker w/o answering my question. So, when an organism dies, is more c12 or c13 left over? Thanks!
