1
Q

A
Attach the membrane to the cytoskeleton of the cell; help maintain cell shape and hold membrane in place when needed.
2
Q

A
Carry out different steps of the metabolic reactions that take place near the membrane.
3
Q
Receptors
A
Act as receptor sites for messenger molecules that signal the cell to stop or start a specific metabolic activity.
4
Q
Transporters
A
Make membrane semipermeable (selective permeability); control movement of substances into and out of the cell.
5
