Density-dependent inhibition is explained by which of the following? 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 cell surface proteins of one cell contact the adjoining cells and they stop dividing. 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.
