35. The molecular chaperone protein BiP assists protein maturation within the rough endoplasmic reticulum lumen by recognizing and binding to

A. Exposed hydrophobic patches on unfolded polypeptides
✓
B. Terminal mannose-6-phosphate residue networks
C. The hydrophilic N-terminal signal sequence
D. O-linked oligosaccharide modifications

📝 Explanation

BiP (Binding Immunoglobulin Protein) uses ATP to mask exposed hydrophobic regions on nascent proteins, preventing aggregation and helping them fold properly.

📖 Additional Information

  • Exposed hydrophobic patches on unfolded polypeptides
  • Terminal mannose-6-phosphate residue networks
