Question

The most notable difference between PrP^C (normal protein) and PrP^Sc (prion protein) is

a. PrP^C is a much longer polypeptide chain, compared to PrP^Sc.

b. PrP^C causes a cell to undergo rapid apoptosis.

c. PrP^c folds appropriately whereas PrP^Sc does not fold correctly.

d. PrP^c is a functional glycolytic enzymewhereas PrP^Sc 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 1

Answer=

The most notable difference between PrP^C (normal protein) and PrP^Sc (prion protein) is

c. PrP^c folds appropriately whereas PrP^Sc does not fold correctly.

Explaination - PrP^c is a normal protein found in brain.In prion diseases normal PrP^c converted into misfolded form PrP^Sc .

PrP^cis alpha helix rich normal protein and PrP^Sc 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.
