Final answer:
The statement is true. The Ubiquitin-proteasome pathway is an important pathway for degrading short-lived proteins important for metabolic adaptation.
Step-by-step explanation:
The statement is true. The Ubiquitin-proteasome pathway is indeed an important pathway for degrading short-lived proteins important for metabolic adaptation.
Ubiquitin is a polypeptide that attaches to proteins, marking them for degradation. The marked proteins are then delivered to the proteasome, which is responsible for breaking down these proteins into small peptide fragments.
This pathway is crucial for maintaining cellular homeostasis by regulating the levels of proteins involved in metabolic adaptation and response to stress.
