They can be removed from the membrane with high salt
They can be found on both the cytoplasmic face and the extracellular face of the plasma membrane
They can be bound at the membrane to either membrane lipids or other membrane proteins
They are immobile in the membrane
They are held at the membrane via ionic interactions with membrane components Properties of peripheral membrane proteins.

The apoptotic cell shrinks in size
The nucleus of an apoptotic cell is smaller and appears darker by light or electron microscopy than the nucleus of a healthy cell
The plasma membrane of an apoptotic cell becomes disrupted
The apoptotic cell fragments into smaller pieces
The phospholipid phosphatidylserine (PS) is exposed o the extracellular face of the plasma membrane of an apoptotic cell

Clathrin cycles between an assembled and unassembled state
Clathrin assembly on a membrane deforms that membrane
LDL receptors only cluster in clathrin-coasted pits after binding LDL
Clathrin clusters LDL receptors via adaptins
Clathrin is not found on caveolae
Mitochondria import proteins co-translationally through contact sites in the membrane
Mitochondria maintain an acidic pH inside the lumen of the intermembrane space.
Mitochondria localize mot of the protein components of the respiratory chains in the inner mitochondrial membrane or the matrix.
Mitochondria pump protons across themitochondrial inner membrane into the matrix
Mitochondria localize their DNA inside the intermembrane space
Forms the mitotic spindle
Forms the contractile ring that separates daughter cells at mitosis
Forms microvilli
Forms lamellopodia
Forms the terminal web
