Question

Density-dependent inhibition is a phenomenon in which crowded cells stop dividing at some optimal density and location. This phenomenon involves binding of a cell-surface protein to its counterpart on an adjoining cell's surface. A growth inhibiting signal is sent to both cells, preventing them from dividing. Certain external physical factors can affect this inhibition mechanism.Select the statement that makes a correct prediction about natural phenomena that could occur during the cell cycle to prevent cell growth.A) As cells become more numerous, they begin to squeeze against each other, restricting their size and ability to allow cell growth.B) As cells become more numerous, the protein kinases they produce begin to compete with each other until only one cell has the proteins necessary for growth.C) As cells become more numerous, the amount of required growth factors and nutrients per cell becomes insufficient to allow for cell growth.D) As cells become more numerous, more and more of them enter the synthesis part of the cell cycle and duplicate DNA to inhibit cell growth.

Answer 1

Option C) As cells become more numerous, the amount of required growth factors and nutrients per cell becomes insufficient to allow for cell growth.

Step-by-step explanation:

The correct statement that predicts a natural phenomenon that could occur during the cell cycle to prevent cell growth is option C) As cells become more numerous, the amount of required growth factors and nutrients per cell becomes insufficient to allow for cell growth.

In density-dependent inhibition, crowded cells stop dividing at some optimal density and location. The phenomenon involves binding of a cell-surface protein to its counterpart on an adjoining cell's surface, sending a growth-inhibiting signal to both cells and preventing them from dividing. As the cells become more numerous, the available growth factors and nutrients per cell become limited, which is one of the factors that can affect this inhibition mechanism.

Answer 2

The correct option is C) As cells become more numerous, the amount of required growth factors and nutrients per cell becomes insufficient to allow for cell growth.

Step-by-step explanation:

During the process of growth of a cell, it requires adequate amount of nutrients and growth factors to develop all the complex organelles and right growth size of the cell.

As the cell number increases, the nutrition required for these cells begins to deplete. This acts as a signal for the body to produce more cells. Once the nutrients and growth factors become abundant again the cells starts its process of growth again.
