Explanation:

1. The first diagram shows ATP powering a membrane protein to move solutes against their concentration gradient, which is transport work.
2. The second diagram shows ATP powering the contraction of a muscle cell, which is mechanical work.
3. The third diagram shows ATP powering the bonding of molecules A and B into a larger molecule, which is chemical work.

Answer:

Top box (solute transport): Transport work
Middle box (muscle contraction): Mechanical work
Bottom box (molecule synthesis): Chemical work
