Question

1 multiple choice 1 point which plasma membrane component can be either found on its surface or embedded in the membrane structure? protein cholesterol carbohydrate phospholipid 2 multiple choice 1 point what is the primary function of carbohydrates attached to the exterior of cell membranes? cell recognition membrane fluidity strengthening the membrane membrane transport

Explanation:

1. Proteins in the plasma membrane can be peripheral (on the surface) or integral (embedded). Cholesterol is mainly embedded to regulate fluidity. Carbohydrates are usually attached to proteins or lipids on the surface. Phospholipids form the basic bilayer structure, with some proteins and other components associated with them. So the answer for the first - question is protein.
2. Carbohydrates attached to the exterior of cell membranes are mainly involved in cell - cell recognition. Membrane fluidity is mainly regulated by cholesterol. Strengthening the membrane is not the main function of these carbohydrates. Membrane transport is mainly the function of proteins. So the answer for the second question is cell recognition.

Answer:

1. A. protein
2. A. cell recognition
