Degradation of cellular unwanted proteins is carried out in _________
A. Proteasomes
B. Lysosome
C. Peroxisomes
D. Ribosomes
The question was asked by my college professor while I was bunking the class.
Question is from Gene Expression Control in division Control of Gene Expression of Cell Biology
Right choice is A. Proteasomes
For explanation I would say: Cellular proteins are degraded in the proteasomes.They are made up of 2 different protein complexes(two α subunit and two β subunit). Lysosomes however degrade extracellular proteins and other macromolecules.
