The most notable difference between PrPC (normal protein) and PrPSc (prion protein) is
c. PrPc folds appropriately whereas PrPSc does not fold correctly.
Explaination - PrPc is a normal protein found in brain.In prion diseases normal PrPc converted into misfolded form PrPSc .
PrPcis alpha helix rich normal protein and PrPSc is beta structure rich insoluble conformer i.e. misfolded.

__Deamination refers to the removal of an amino group from an amino acid. One mechanism for this removal is _transamination , in which the amino group is transferred to an acceptor molecule.
b. Deamination; transamination
explaination-
Deamination - Is the process of the removal of an amino group from an amino acid.
Transamination -is the process of transfer of the amino group from a donor molecule to acceptor molecule.
