Question

what is a difference between atp and adp molecules? (4 points) adp is only made in plants, while atp is made in both plants and animals. atp has three phosphate groups, while adp has two phosphate groups. atp molecules provide less energy to the cell than adp molecules. adp can be used to directly power movement, while atp cannot.

Explanation:

ATP (adenosine - triphosphate) has three phosphate groups and is the main energy - carrying molecule in cells. ADP (adenosine - diphosphate) has two phosphate groups. When ATP donates energy, it loses a phosphate group and becomes ADP.

Answer:

ATP has three phosphate groups, while ADP has two phosphate groups.
