Answer the following question given this paragraph: 

Peripheral membrane proteins are proteins that are only temporarily associated with the membrane. They can be easily removed, which allows them to be involved in cell signaling. Peripheral proteins can also be attached to integral membrane proteins, or they can stick into a small portion of the lipid bilayer by themselves. Peripheral membrane proteins are often associated with ion channels and transmembrane receptors. Most peripheral membrane proteins are hydrophilic.


Q: What type of proteins are only temporarily associated with the membrane?

 Choices:

- visual membrane proteins

- sensitive rod proteins

- peripheral oxidation proteins

- peripheral membrane proteins

A:
peripheral membrane proteins
