Q1Domain Verified
Which of the following mechanisms is LEAST likely to be a direct downstream effector of mTORC1 inhibition leading to autophagy initiation, as detailed in "The Complete Autophagy Activation Course 2026"?
Activation of ATG proteins involved in vesicle nucleation.
Increased lysosomal fusion with autophagosomes.
Inhibition of BECN1 (Beclin-1) dissociation from the Bcl-2 complex.
Dephosphorylation and activation of ULK1 complex components.
Q2Domain Verified
In the context of "The Complete Autophagy Activation Course 2026," what is the primary role of ATG13 in the autophagy machinery, particularly concerning its interaction with ULK1 and mTORC1?
To directly bind to and activate lysosomal hydrolases.
To facilitate the formation of the phagophore membrane.
To act as a scaffold protein that integrates signals from mTORC1 and other nutrient sensors to regulate ULK1 activity.
To tag damaged organelles for degradation by the proteasome.
Q3Domain Verified
According to "The Complete Autophagy Activation Course 2026," which of the following represents a key difference between macroautophagy and chaperone-mediated autophagy (CM
Macroautophagy involves the formation of double-membraned vesicles (autophagosomes), while CMA directly translocates substrates across the lysosomal membrane via the LAMP2A receptor.
CMA is constitutively active, whereas macroautophagy is primarily induced by stress.
in terms of substrate recognition and delivery? A) Macroautophagy primarily targets soluble cytosolic proteins, while CMA degrades aggregated proteins.
Macroautophagy relies on specific KFERQ-like motifs for substrate recognition, while CMA uses LC3 conjugation.
