Question

multiple choice 1 point what type of molecule is sometimes found spanning a cells plasma membrane with part of the molecule on one side of the membrane, part embedded in the membrane, and part on the other side? rna protein phospholipid carbohydrate

Explanation:

Proteins can be integral membrane proteins that span the cell's plasma membrane with parts on either side, embedded in the membrane, etc. Carbohydrates are often attached to proteins or lipids on the outer - surface of the membrane. Phospholipids form the basic structure of the membrane bilayer and do not typically span in the described way. RNA is not a common component spanning the plasma membrane in this context.

Answer:

C. protein
