A. Possess negative charges due to phosphate groups
B. Carry short, branched oligosaccharide chains exposed to the exterior
✓
C. Are synthesized completely within the nuclear matrix
D. Can act as independent ATP-synthase complexes

📝 Explanation

Both classes contribute to the structural cell coat by projecting their hydrophilic branched sugar chains into the extracellular space.
