Which of the following is not a function of the eukaryotic glycocalyx?

• A. Providing a barrier to pathogens
• B. Protection against mechanical damage
• C. Facilitating cell-cell recognition
• D. Energy production

Answer: (D)

Verified step by step guidance

1. Understand the role of the glycocalyx: The glycocalyx is a glycoprotein and glycolipid covering that surrounds the cell membranes of some eukaryotic cells. It plays several roles, including protection, immunity to infection, and cell recognition.
2. Identify the functions of the glycocalyx: The glycocalyx provides a barrier to pathogens, protects against mechanical damage, and facilitates cell-cell recognition. These functions are related to its structure and composition, which includes carbohydrates that can interact with other cells and molecules.
3. Consider the process of energy production: Energy production in eukaryotic cells primarily occurs in the mitochondria through processes such as cellular respiration, which involves the conversion of glucose and oxygen into ATP (adenosine triphosphate).
4. Compare the functions: Compare the listed functions of the glycocalyx with the process of energy production. Note that energy production is a metabolic process that occurs within the cell, specifically in the mitochondria, and is not related to the glycocalyx.
5. Conclude which function is not associated with the glycocalyx: Based on the understanding that energy production is a function of the mitochondria and not the glycocalyx, identify that energy production is not a function of the eukaryotic glycocalyx.
