Which of the following functions of membrane proteins is important in tissue formation during embryonic development in animals?

• A. Membrane proteins attach the membrane to the cytoskeleton.
• B. Membrane proteins possess enzymatic activity.
• C. Membrane proteins form channels, which move substances across the membrane.
• D. All of the listed responses are correct.
• E. Membrane proteins with short sugar chains form identification tags that are recognized by other cells.

Answer: (E)

Verified step by step guidance

1. Understand the role of membrane proteins in cellular functions. Membrane proteins are crucial for various cellular processes, including communication, transport, and structural support.
2. Identify the specific function related to tissue formation during embryonic development. In this context, cell recognition and communication are key processes.
3. Recognize that membrane proteins with short sugar chains, known as glycoproteins, play a role in cell recognition. These glycoproteins act as identification tags that are recognized by other cells.
4. Consider how cell recognition is essential during embryonic development. Cells need to identify and communicate with each other to form tissues and organs correctly.
5. Conclude that the function of membrane proteins forming identification tags is crucial for tissue formation during embryonic development, as it facilitates proper cell recognition and communication.
