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, membrane ion channels are examples of integral membrane proteins. They are embedded within the lipid bilayer of a cell's membrane and mediate the passage of ions across the membrane in a highly regulated manner.
What membrane proteins are integral proteins?
Integral membrane proteins include transmembrane proteins, which span the entire lipid bilayer, and lipid-anchored proteins, which are attached to the membrane through lipid molecules. These proteins are essential for various cellular functions such as cell signaling, transport, and structural support. Examples include ion channels, transporter proteins, and receptors.
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 are 4 types of proteins found in cell membrane?
Integral membrane proteins: embedded within the lipid bilayer. Peripheral membrane proteins: bound to the membrane surface. Receptor proteins: involved in cell signaling and communication. Channel proteins: facilitate the passage of ions and molecules across 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.
What are some modulators of membrane fluidity?
Some moderators of membrane fluidity are the proteins embedded in it and cholesterol molecules also.

What Proteins that penetrate both layers of the phospholipid membrane?
Transmembrane proteins are proteins that span both layers of the phospholipid bilayer. These proteins have regions that interact with the hydrophobic core of the membrane, allowing them to pass through and interact with both the inner and outer environments of the cell. Examples include ion channels and transporters.
What type of proteins are used in facilitated diffusion?
Facilitated diffusion involves the use of integral membrane proteins known as carrier proteins or channel proteins to help transport specific molecules across the cell membrane. These proteins provide a pathway for the molecules to cross the lipid bilayer more efficiently than simple diffusion.
What biomolecule helps transport molecules across the membrane?
proteins
What component of a phospholipid membrane helps the cell interact with its polar watery environment?
Membrane proteins.
What kind of protein helps some substances cross the cell membrane?
Carrier proteins help facilitate the movement of certain substances across the cell membrane by binding to specific molecules and carrying them across. These proteins undergo conformational changes to transport the substances across the membrane.
