Membrane proteins? Various functions

The plasma membrane is an essential part of the cell. It surrounds the cell and has a unique chemical combination that allows for the transport of molecules into and out of the cell.Figure 2. The eukaryotic plasma membrane is a phospholipid bilayer with proteins and cholesterol embedded in it. by OpenStax (CC BY-SA 4.0)Which of the following statements describes the chemical composition of the plasma membrane and the permeability of the membrane?Elimination ToolSelect one answerAThe plasma membrane is hydrophilic on the outside layers and hydrophobic in the inside layers. The plasma membrane is permeable.BThe plasma membrane is hydrophobic on the outside layers and hydrophilic in the inside layers. The plasma membrane is permeable.CThe plasma membrane is hydrophobic on the outside layers and hydrophilic in the inside layers. The plasma membrane is semi-permeable.DThe plasma membrane is hydrophilic on the outside layers and hydrophobic in the inside layers. The plasma membrane is semi-permeable.

Peripheral proteins are attached to either inner or outer surface of cell membrane

Which of the following is not true of membrane proteins?Membrane proteins may help the cell in differentiating between self and non-self cells.Membrane proteins are often dedicated to transfer information between the cell interior and its exterior.Membrane phosphoproteins are ones that are attached to branched carbohydrates.Membrane proteins may form channels to allow the passive transport of substances.

The function of membrane proteins is to:W. act as carrier molecules for various solutes.X. bind to ligands (chemicals).Y. regulate the passage of ions.Z. store cellular nutrients.Question 11
