The duplication of centrioles occurs at the same time as DNA duplication for the cell cycle; that is, in the S phase of interphase.
Answer:
ATP provides energy coupling between exergonic and endergonic reactions.
Explanation:
- Adenosine triphosphate is an important molecule found in the cells and its role is to transport energy that is necessary for the cell or metabolic activities. These activities include muscle contraction and nerve impulse propagation.
- The ATP provides energy to both the energy consumption actions and energy-releasing reactions and thus needs a small amount of input of energy. The chemical bonds on breaking provide energy for cells to work.
