can often move within the lateral plane of the membrane

can flip/flop across the membrane bilayer altering their inside/outside orientation

can only be removed by disruption of the membrane

have hydrophilic and hydrophobic parts

take the form of a helix as they pass through the membrane

Through a series of modifications in the cis-, medial, and trans-Golgi networks before the protein is sorted and stored in secretory vesicles

Through a series of modifications in the cis-, medial, and trans-Golgi networks before the protein is sorted and released into the cytoplasm

Involves only modifications in cis- and trans-Golgi networks before the protein is sorted and released into the cytoplasm

Through a series of modifications in the cis-, medial, and trans-Golgi networks and fusion with the cell membrane

Through a series of modifications in the secretory vesicles that progress through the Golgi apparatus before release into the cytoplasm

allow the movement of ions across the membrae

determine the type of ion which can cross through the channel

are embedded in only one side of the membrane

are responsible for gating a channel

can be removed without disrupting the membrane

To assist in the production of ATP

To help digest waste products and cell debris

To give the cell structure and aid in movement of substances

To increase the viscosity of the cell membrane

To modify proteins and lipids in preparation for release
