From the given options, the functions of ATP include:
- To power transport across cell membranes.
- To power the movement of cells.
- To drive energetically unfavorable reactions.
Adenosine Triphosphate (ATP) is defined as the energy molecule that is derived from the metabolic oxidation of glucose.
This ATP is used for a variety of processes which include:
- Active transport: It provides the energy that is needed to move materials against a concentration gradient. This leads to the transport of the materials across cell membranes.
- Movements: Muscle contraction and ciliary movement which brings about movement in cells, requires energy from the hydrolysis of ATP.
- Thermodynamically unfavorable reaction: This can be driven by the hydrolysis of ATP energy molecule in a cell.
