Like lipids, membrane proteins have the same ability to act like a fluid and move around in the membrane.

• A. True
• B. False

Answer: (A)

Verified step by step guidance

1. Understand the fluid mosaic model of the cell membrane, which describes the membrane as a dynamic and flexible structure composed of lipids and proteins.
2. Recognize that lipids in the membrane are not static; they can move laterally within the bilayer, contributing to the fluid nature of the membrane.
3. Learn that membrane proteins are embedded within the lipid bilayer and can also move laterally, similar to lipids, allowing for fluidity and flexibility in the membrane.
4. Consider the role of membrane fluidity in cellular processes such as signaling, transport, and cell movement, which require the dynamic movement of proteins within the membrane.
5. Conclude that both lipids and proteins contribute to the fluid nature of the membrane, supporting the statement that membrane proteins can move around in the membrane like lipids.
