Question

Abnormal or misfolded intracellular proteins are tagged by ________ molecules which targets them for destruction by the ________?

1) parkin - ubiquitin
2) α-synuclein - parkin
3) ubiquitin - proteasomes
4) parkin - Lewey bodies
5) ubiquitin - neurofilaments

Answer 1

Ubiquitin molecules target abnormal or misfolded intracellular proteins for destruction by proteasomes.

Step-by-step explanation:

Abnormal or misfolded intracellular proteins are tagged by ubiquitin molecules which targets them for destruction by the proteasomes.
