When stress conditions arise, or when protein synthesis threatens to overwhelm the protein-folding capacity of the ER, unfolded proteins can accumulate. These conditions trigger the unfolded protein response (UPR)

a) unfolded protein response ensures to reduces the rate of protein synthesis by mTOR pathway

b) Amyloid aggregates that form before the UPR can come into play may be removed. Some are degraded by autophagy

c) Amyloid aggregates that can be removed by other mechanism such as lysosomal degradations

d)  UPR also bring the various systems into alignment by increasing the concentration of chaperones in the oxygen deprived conditions

In the amoeba Dictyostelium discoideum, cAMP acts as an extracellular signalling molecule and binds to and signals via a G protein–coupled receptor; it is not a second messenger. Amoeba cells were transfected with genes encoding two fusion proteins: a Gα fused to cyan fluorescent protein (CFP), and a Gβ fused to yellow fluorescent protein (YFP). CFP normally fluoresces 490-nm light; YFP, 527-nm light. In which conditions fluorescence
energy transfer occur from CFP to YFP?
