The cell cycle is composed of S (synthetic) phase and M (Mitotic) phase. In between are G1 and G2 phases. cyclin-dependent kinases propel cell division. Their activation results in the progression of a cell from one phase to another while their inactivation arrests a cell in a phase. In case of damage to DNA during a cell cycle, transcription factors p53 (a renowned tumor suppressor) are recruited. P53 inhibits cyclins-dependent kinases and also induces cell apoptosis if DNA is not repaired.

Which homeostatic process requires energy to move particles across the plasma membrane?

Pani-rosa [81]

Active transport requires energy because unlike osmosis and diffusion which are passive transport methods which sees where the particles are moving along the concentration gradient, in active transport, the particles are moving against the concentration gradient and as such energy through ATP is needed for the particles to be transported.
