In the cell cycle, controlled degradation of regulatory proteins occurs via the
A)kinase inhibition pathway.
B)P450 - protease pathway.
C)ubiquitin- proteosome pathway.

E)none of the above

Question

Quizplus · Accepted Answer

The ubiquitin-proteosome pathway is responsible for the controlled degradation of regulatory proteins in the cell cycle. Proteins are tagged with ubiquitin and then degraded by the proteasome.
