Use Figure 3−29B to illustrate the following reaction driven by the hydrolysis of ATP: X + ATP → Y + ADP + Pi

A. In this case, which molecule or molecules would be analogous to (i) rocks at the top of the cliff, (ii) broken debris at the bottom of the cliff, (iii) the bucket at its highest point, and (iv) the bucket on the ground?

B. What would be analogous to (i) the rocks hitting the ground in the absence of the paddle wheel in Figure 3−29A and (ii) the hydraulic machine in Figure 3−29C?
