Question

2 which of the following correctly list the four components of a plasma membrane and explain their function?
phospholipids: form the bilayer; carbohydrates: help in adhesion; cholesterol: provide flexibility; integral proteins: form protein channels
phospholipids: form the bilayer; carbohydrates: part of the cells recognition sites; cholesterol: provide flexibility; peripheral proteins: part of the cells recognition sites
phospholipids: form the bilayer; carbohydrates: help in adhesion; cholesterol: form transporters; integral proteins: provide flexibility; peripheral proteins: part of the cells recognition sites.
phospholipids: form the bilayer; carbohydrates: function as adhesion; cholesterol: provide flexibility to the membrane; integral proteins: form protein channels; intermediate filaments: part of the cells recognition sites.

Explanation:

• Phospholipids form the bilayer of the plasma membrane.
• Carbohydrates are part of the cell's recognition sites.
• Cholesterol provides flexibility to the membrane.
• Integral proteins form protein channels.
• Peripheral proteins help in adhesion.

Answer:

Phospholipids: form the bilayer; Carbohydrates: part of the cell's recognition sites; Cholesterol: provide flexibility; Integral proteins: form protein channels; Peripheral proteins: help in adhesion.
