Question

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 molecule, which she labels ADP. She attaches the block to a spring and then compresses the spring between the block and a smaller round paperweight. What does the coiled spring represent in an actual molecule of ATP?

Answer 1

The covalent bond between the middle phosphate and the last phosphate.

Step-by-step explanation:

When the student builds the model of an ATP molecule form some scraps.She also used a block of wood for the bulk of the molecule labelled as ADP.So when the block is connected to the spring and then compressed between the block and a paperweight here the coil spring represents the covalent bond between the middle and the last phosphate.
