Density-dependent inhibition is explained by which of the following processes?
A) As cells become more numerous, they begin to squeeze against each other, restricting their size.
B) As cells become more numerous, the cell surface proteins of one cell contact the adjoining cells, and they signal each other to stop dividing.
C) 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.
D) As cells become more numerous, the level of waste products increases, which slows metabolism and inhibits growth.

Question

Quizplus · Accepted Answer

Density-dependent inhibition is the process by which cell division slows down or stops as cells in a culture become more crowded. This is often mediated by cell surface proteins of one cell contacting the adjoining cells, and they signal each other to stop dividing.
