Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Cell adhesion is important for cell culture.
Specific proteins promote cell attachment.
Step 2: Key Formula or Approach:
No specific formula.
Need to know cell adhesion proteins.
Step 3: Detailed Explanation:
Fibronectin is a glycoprotein that promotes cell attachment.
It mediates cell-substrate adhesion.
Collagen is a structural protein.
Transferrin is for iron transport.
FGF is a growth factor.
Thus, fibronectin promotes cell attachment.
Step 4: Final Answer:
Fibronectin promotes attachment of cells to the substrate.
Hence, the correct option is (B).
