The most notable difference between PrPC (normal protein) and PrPSc (prion protein) is a. PrPC is a much longer polypeptide chain, compared to PrPSc. b. PrPC causes a cell to undergo rapid apoptosis. c. PrPc folds appropriately whereas PrPSc does not fold correctly. d. PrPc is a functional glycolytic enzymewhereas PrPSc is nonfunctional. Where is the electron transport chain located in bacterial cells? a. Plasma membrane b. Periplasm c. Mitochondrial inner membrane d. Mitochondrial outer membrane ______________ refers to the removal of an amino group from an amino acid. One mechanism for this removal is _____________, in which the amino group is transferred to an acceptor molecule. a. Deamination; hydrolysis b. Deamination; transamination c. Transamination; deamination d. Hydrolysis; transamination

Answer

Answer= 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. ——————————————————————————————————————————- Where is the electron transport chain located in bacterial cells? a. Plasma membrane Explaination- In bacterial cells electron transport chain is located in their plasma or cell membrane. ————————————————————————————————————————————— __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.
