what are the types of proteins present in cell membrane?
Answers
Answer:
Based on their structure, there are main three types of membrane proteins: the first one is integral membrane protein that is permanently anchored or part of the membrane, the second type is peripheral membrane protein that is only temporarily attached to the lipid bilayer or to other integral proteins, and the third one is lipid-anchored proteins.

→6 Important Types of Membrane Proteins
•Peripheral (Extrinsic) Proteins.
•Integral (Intrinsic) Proteins.
•Integral Proteins That Span the Membrane.
•Asymmetric Distribution of Membrane Proteins.
•Mobility of Membrane Proteins.
•Enzymatic Properties of Membrane Proteins.
•Ectoenzymes and Endoenzymes.
•Isolation and Characterization of Membrane Proteins.

Answer:
Membrane proteins represent about a third of the proteins in living organisms. Based on their structure, there are main three types of membrane proteins: the first one is integral membrane protein that is permanently anchored or part of the membrane, the second type is peripheral membrane protein that is only temporarily attached to the lipid bilayer or to other integral proteins, and the third one is lipid-anchored proteins (Fig. 1). Here we only describe the first two types of membrane protein.
