Question

The cell membrane controls the traffic of molecules into and out of the cell, prevents the entry of toxic material into the cell and permits selective uptake of nutrients. Which property of the membrane can this be attributed to? A) Carbohydrates present on the membrane
B) Lipid bilayer of the membrane
C) Membrane fluidity
D) Semi-permeable nature of the membrane

Answer 1

"Semi-permeable nature of the membrane" is the property of the membrane among the choices given in the question that this can be attributed to. The correct option among all the options that are given in the question is the fourth option or option "D". I hope that the answer has actually come to your help.

Answer 2

Answer:

D) Semi-permeable nature of the membrane

Explanation:

The plasma membrane is a semi-permeable structure of the cell, due to its selective permeability. This feature allows the cell to exchange substances with the extracellular medium, such as glucose, oxygen, carbon dioxide, ammonia, water and mineral salts, for example.

This exchange of substances is fundamental for cells, since it absorbs, produces, consumes and eliminates many different types of substances during their metabolism.

In other words, the semi-permeable nature of the cell membrane selects what should enter and leave cells, controlling the concentrations of substances in the intracellular and extracellular media.
