Question

Density-dependent inhibition is explained by which of the following? As cells become more numerous, they begin to squeeze against each other, restricting their size and ability to produce control factors. As cells become more numerous, the level of waste products increases, eventually slowing down metabolism. As cells become more numerous, the protein kinases they produce begin to compete with each other, such that the proteins produced by one cell essentially cancel those produced by its neighbor. As cells become more numerous, the surface proteins of one cell contact the adjoining cells and they stop dividing. As cells become more numerous, more and more of them enter the S phase of the cell cycle.

Explanation / Answer

c.If a cell is crowded it will not divide. Cells will stop dividing when they are in contact with others cells.This is called density dependent inhibition or contact inhibition.It occurs as the protein kinases they produce begin to compete with each other, such that the proteins produced by one cell essentially cancel those produced by its neighbours.
