Question
Which statement is NOT true about the proteins in the plasma membrane?
-Proteins may be attached to the inner surface of the plasma membrane.
-The hydrophobic portion of a protein is embedded within the membrane.
-Some peripheral proteins are connected to cytoskeletal filaments.
-Integral proteins are responsible for membrane functions.
-Glycoproteins contain carbohydrate chains that are oriented toward the inner surface of the membrane.(CORRECT)
can someone explain why the last answer is correct? Thanks!

Answers
The last answer is correct because glycoproteins contain carbohydrate chains that are oriented toward the outer surface of the membrane, not the inner surface. This is because the carbohydrate chains are hydrophilic and need to be exposed to the aqueous environment outside the cell.
