ATPase, Na/K channels, hormone receptors, ABC transporters are a few examples. In addition proteins that participate in electron transport chain (in mitochondria) are also membrane proteins that make ATP at the end by ATPase. Nup358 is a membrane protein in nucleus.

Are membrane ion channels are examples of integral membrane proteins?
yes they are
What are cell-membrane proteins?
Membrane proteins are important to carry out the process of selective transport across cells. Na/K channel proteins, ABC transsporters, ATP synthase, ETC chain proteins are some good examples. They mostly cost energy to transport a molecule (active transport) and other protein actually synthesize ATP (ATP synthase)
What are some modulators of membrane fluidity?
Some moderators of membrane fluidity are the proteins embedded in it and cholesterol molecules also.
What kind of protein helps some substances cross the cell membrane?
Channel proteins.
Integral proteins in the plasma membrane?
These are proteins that are permanently attached to or in the cell membrane via its hydrophobic domains interacting with the membrane's phospholipids.
Are membrane ion channels are examples of integral membrane proteins?
yes they are
How can a lipid bilayer be fluid yet asymetrical?
There are proteins embedded in the membrane also. Some of these proteins exist on the aqueous side (outside) while others are only embedded on the inside. These are called peripheral membrane proteins. Some proteins go span the entire length of the lipid bilayer and are called transmembrane proteins. Peripheral membrane proteins are only temporarily attached and can become free by some types of stresses (i.e. detergents, solvents etc.). Integral membrane proteins are proteins that are permanently attached to the membrane.
Is proteins production part of membrane proteins?
Membrane proteins and all other proteins are produced in cytoplasm. The proteins targeted to membranes by specific signals. Golgi vesicles transport the proteins to membrane. Not all proteins are membrane proteins
Where are membrane proteins are found?
Surprisingly, membrane proteins are found in or attached to the membrane.

Integral proteins in the plasma membrane?
These are proteins that are permanently attached to or in the cell membrane via its hydrophobic domains interacting with the membrane's phospholipids.
What type of proteins are used in facilitated diffusion?
they can be of varying types. examples include like porins, aquaporins and ion channles.
What membrane proteins are integral proteins?
Membranes bound within the cell membrane. Integral proteins extend from one side of the membrane to the other.
What are two roles of the membrane proteins?
There are two main roles of the membrane proteins. Membrane proteins act as channels across the lipid bilayer. They also act as carrier molecules that transfer substances across the membrane.
What organelle gathers proteins and has no membrane?
Ribosomes doesn't has no membrane it make their proteins.
