TOXICOLOGY: A. MOLECULAR REPAIR
(Repair of Proteins)

1 occurs by means of electron transfer from
cytochrome b5, which is then regenerated by a NADH dependent cytochrome b5 reductase.

2 are synthesized in large quantities in RESPONSE TO
PROTEIN DENATURATION

3 Damaged proteins can either be __, following ubiquitination in proteasomes.

4 Proteins can be eliminated by
__ in lysosomes.
