4.

1. molecule of

6.
7.
8.

Explanation:

The molecule shown is related to energy - storage in cells. Adenosine tri - phosphate (ATP) has a structure with adenine, ribose sugar, and three phosphate groups. Adenosine diphosphate (ADP) has adenine, ribose, and two phosphate groups. The hexagon - shaped structure is adenine, the pentagon - shaped is ribose, and the circles are phosphate groups.

1. Adenine is the nitrogen - containing base represented by the hexagon.
2. Ribose is the sugar, the pentagon - shaped structure.
3. Phosphate groups are the circular structures.
4. ATP has more energy stored in its high - energy phosphate bonds compared to ADP. When ATP loses a phosphate group, it becomes ADP and releases energy.

Answer:

1. Adenine
2. Ribose
3. Phosphate
4. Energy (stored in ATP's phosphate bonds)
5. Adenine
6. Ribose
7. Phosphate
8. Energy (stored in ATP's phosphate bonds)
