Question

Which type of membrane protein is MOST likely to be involved in cell-cell recognition and adhesion?

K SURESH KUMAR · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Membrane protein functions
 **Related Topics**: Cell adhesion, glycocalyx, cell signaling
 **Prerequisites**: Understanding of different types of membrane proteins and their locations within the cell membrane.
## SOLUTION PATHWAY
**Given Information**:
The question asks about the type of membrane protein most involved in cell-cell recognition and adhesion.
**Method & Steps**:
1. Consider the functions of different membrane proteins.
  Reasoning: Peripheral membrane proteins are loosely associated with the membrane and are less likely to be involved in strong cell-cell interactions. Integral membrane proteins can be involved, but their role in recognition and adhesion depends on their structure and modifications.
  Formula/Rule: N/A
2. Analyze the role of glycosylation.
  Working: Glycosylation, the addition of carbohydrate chains to proteins (forming glycoproteins), is crucial for cell-cell recognition.  The carbohydrate chains act as markers that other cells can recognize.
  Key Point: Glycoproteins are often found on the cell surface, where they can interact with other cells.
3. Determine the most likely protein type.
  Result: Glycoproteins are the most likely type of membrane protein involved in cell-cell recognition and adhesion due to their carbohydrate modifications.
  Verification: The carbohydrate chains on glycoproteins provide specific binding sites for other molecules, facilitating cell-cell interactions.
 ## OPTION ANALYSIS
A :x: Peripheral membrane proteins are loosely bound and not directly involved in strong cell-cell interactions.
B :x: Integral membrane proteins without glycosylation lack the specific carbohydrate markers necessary for cell recognition and adhesion.
C ✓: Glycoproteins, with their carbohydrate chains, are key players in cell-cell recognition and adhesion, making them the most likely candidate.
D :x: Channel proteins facilitate the transport of molecules across the membrane and are not primarily involved in cell-cell recognition or adhesion.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing the roles of different membrane proteins:  It's important to understand the specific functions of each type of membrane protein.
  2.Overlooking the importance of glycosylation: Glycosylation is a crucial modification for many cell surface proteins involved in recognition and adhesion.
 **Quick Tips**:
  1.Remember that carbohydrate chains on glycoproteins are essential for cell-cell recognition.
  2.Associate glycoproteins with cell surface markers and adhesion molecules.
