Cell signalling cascade, membrane transfer of molecules, etc.
Proteins in the cell membrane serve several functions, including transport of molecules, cell signaling, cell recognition, and cell adhesion. They are not primarily involved in providing energy for the cell.
Extracellular membrane receptors are used by peptide hormones and protein hormones, which cannot pass through the cell membrane due to their size or composition. These receptors are located on the cell surface and trigger a signaling cascade inside the cell upon hormone binding, leading to physiological responses.
When protein membrane receptors are activated, they usually undergo a conformational change, which triggers a downstream signaling cascade. This cascade can involve the activation of intracellular proteins or the production of second messengers, leading to a variety of cellular responses such as gene transcription, enzyme activation, or changes in cellular metabolism. Ultimately, the activation of protein membrane receptors initiates a cellular response to the signaling molecule that bound to the receptor.
Yes, surface receptors are made of protein units in cells.
Receptors are proteins on the cell membrane that are used to receive signals

Membrane proteins have many different functions; many are involved in transport across the cell membrane, such as channels, carriers and pumps (e.g .the Na/K-ATPase and P-glycoprotein), others are hormone receptors (e.g. EGFR and the insulin receptor) or confer structure to the cell membrane.
The functions can vary greatly, the fact that its an integral protein limits the functions but there are still many different functions. Ill go through a few functions of integral transmembrane proteins. Transportation. Integral proteins can transport molecules and ions through the membrane, facilitated or active transport are two such transport functions. The protein can also act as ion channels which help the cells to keep the ion gradient at a good level (varies greatly for different ions). The protein can also act as receptors for different hormones or neural signals. The integral proteins can also be cytoskelleton, which function is to connect different cells to eachother, or they can be flagells, villi or microvilli.

Neurotransmitters attach to specific proteins called receptors on the cell membrane. These receptors are typically ligand-gated ion channels or G protein-coupled receptors that initiate cellular responses when neurotransmitters bind to them.
A globular protein in a cell membrane can serve various functions such as transporting molecules across the membrane, acting as receptors for signaling molecules, or assisting in cell adhesion. These proteins usually have a compact, rounded shape that allows them to interact with other molecules in a specific manner.

umami is actually detected by G protein-coupled receptors in the cell membrane of the taste buds in our tongue.
Proteins in the cell membrane serve various functions such as transporting molecules in and out of the cell, acting as receptors for signaling molecules, and providing structural support for the membrane. They also help in cell-cell communication and adhesion, as well as in cell recognition and identification.
