Chapter 24, Problem 108A

Interpretation Introduction

Interpretation: To explain the reason behind the stopping of cell growth when the dietary intake is insufficient.

Concept introduction: Growth and development are critical for long-term health. Dietary intake requirements are very crucial for the human body to sustain both maintenance and high rates of tissue development.

Answer to Problem 108A

Cell growth stops if there is an insufficient amount of dietary nutrients taken as the body lacks the amount of protein that a body needs for the growth of cells and tissues.

Explanation of Solution

Nutrients play a vital role in the functioning of the human body. Nutrient intake is beneficial in the growth of a cell as they provide energy, also helps in regulating chemical processes in the body, and contributes to giving structure to the body.

If the intake of nutrients is insufficient, then the growth of the cell stops. In growing a cell, the enzyme that participates in RNA polymerase I, it increases its activity and then facilitates the production of proteins needed for this process and when the cell stops growing, the activity gets stops which further stops the production of proteins (dietary nutrients).

Therefore, a sufficient amount of nutrients must be taken in order to function in the growth of a cell.

Conclusion

Cell growth stops if there is an insufficient amount of dietary nutrients taken as the body lacks the amount of protein that a body needs for the growth of cells and tissues.
