Question

question 7 select the functions of membrane proteins: transport in and out of the cell cell - cell recognition maintain the cell shape intercellular joining

Explanation:

Membrane proteins have several functions. Transport proteins help move substances in and out of the cell. Glycoproteins on the cell - surface are involved in cell - cell recognition. Some membrane proteins are also involved in intercellular joining. Maintaining cell shape is mainly the function of the cytoskeleton, not membrane proteins.

Answer:

Transport in and out of the cell, Cell - cell recognition, Intercellular joining
