Question

You decide to further analyze the nature of the proteins found within the membrane of the skeletal muscle cell that you extracted. You find that this cell lacks transmembrane proteins. Which loss of function would you expect to observe in this cell based on this observation?

A) an inability to transport ions, nutrients, and other substances across the membrane
B) a loss to the membrane's selective permeability
C) a loss of a membrane flexibility
D) a complete lack of cell surface markers and glycocalyx formation

Answer 1

A) an inability to transport ions, nutrients, and other substances across the membrane

Step-by-step explanation:

Some of the transmembrane proteins present in the plasma membranes serve as carries, channels or pumps. These proteins allow the active or passive movement of charged ions, polar and large substances across the membrane. These substances can not cross the inner non-polar core of the membrane. If a plasma membrane of a particular cell lacks trans-membrane proteins, it would not be able to move the above-mentioned substances in or out of the cells.
