A student builds a model of an atp molecule out of some scraps she finds at home. she uses a block of wood for the bulk of the m

olecule which she labels adp. she attaches the block to a spring and then compresses the spring between the block and a smaller round paper weight. what does the coiled spring represent in an actual molecule of atp?a) the covalent bond between the last phosphate and the middle phosphateb) the adenine partc) the covalent bond between the ribose and the first phosphated) the very last phosphate groupe) the ribose sugar

Answer:

a) the covalent bond between the last phosphate and the middle phosphate

Explanation:

The ADP is composed by a molecule of Adenine, Ribose and two Phosphate groups. The addition of a paper weight in the spring represents the last phosphate added in a ADP, resulting in a ATP. The last phosphate connected with Ribose by a covalent bond, represented by the round paper weight connected to a spring, can be easily detached in order to provide energy to the cell by a process called dephosphorylation. The spring compressed represents the energy of the bond. In the model the compressed spring is represents the potential energy, but in the bond the energy is chemical, which will lead into a electron transference reaction.
