(Choice C) C Nucleic acids freely move across the cell membrane. (Choice D) D Polar amino acids freely move across the cell membrane. What is the best description of the selective permeability of a cell?Selective permeability of the cell membrane refers to its ability to differentiate between different types of molecules, only allowing some molecules through while blocking others.
Which of the following statements best explains how the cell membrane selectively permeable?Which statement best explains what selectively permeable means? The cell membrane lets certain substances enter the cell and keeps certain substances out of the cell.
What does it mean for the cell membrane to have selective permeability?The membrane is selectively permeable because substances do not cross it indiscriminately. Some molecules, such as hydrocarbons and oxygen can cross the membrane. Many large molecules (such as glucose and other sugars) cannot. Water can pass through between the lipids. Ions such as H+ or Na+ cannot.
Which best describes the permeability of a membrane?Permeability is the condition of being capable of having materials flow into and out of a membrane. The permeability of a cell membrane is determined by how easily a molecule can diffuse across the membrane. Usually, only molecules that are fat- soluble can permeate across a cell membrane.
