During the cell cycle, specifically g1 interphase, a cell must reach a sufficient size and produce enough atp in order to

Double the amount of DNA and keep normal function at the same time

Explanation:

Interphase is a phase of the cell cycle, the main goal of the cell in this phase is to growth in order to give space to double the amount of DNA. The first and most significant growth happens during a phase known as G1, during it the centromere and the other components are made while performing normal function, therefore their normal production of ATP must continue.
