1) how does the timing and location of Arf1-GTP hydrolysis contribute the transport of COPI coated vesicles? 2) Consider cargo proteins that are destined for secretion to the extracellular space. For each of the following pairs of mutations or conditions, predict where the cargo will end up (ex. in the cytoplasm, a specific organelle, transport vesicles, multiple places, extracellular space) for: (i) & (ii) Each individual condition; & (iii) The combination of both. A.(i) Normal Sar1 is mutated so that...
