During cellular respiration, the bonds of food molecules are broken, so energy can be released to fuel other cellular processes. In order for this to occur, which of the following statements must be true? A.
New compounds with higher-energy bonds must be formed when the low-energy bonds in food molecules are broken.
B.
The energy in the new compounds that are formed must be equal to the energy in the bonds of the food molecules.
C.
New compounds with lower-energy bonds must be formed when the high-energy bonds in food molecules are broken.
D.
The new compounds that are formed must be more complex than the food molecules that were broken down.

One function of the poly-a tail on eukaryotic mrna sequences is to the mrna be transported from the nucleus to the cytoplasm. prokaryotic mrna also has a poly-a tail. choose the best explanation of the prokaryotic poly-a tail. a. prokaryotic poly-a tails are composed of a different molecular structure compared with eukaryotic poly-a tails. b. prokaryotic poly-a tails have the same functions as eukaryotic poly-a tails, because this process is highly conserved throughout different species. c. prokaryotic poly-a tails aren't important, because prokaryotes don't have nuclei. d. prokaryotic poly-a tails have other functions,because prokaryotes don't have nuclei.
