A protein that is normally localized in the cytoplasm has been engineered so that it will be secreted from the cell instead.
Which of the following represents the most likely pathway for the protein after it has been completely synthesized?

A. sER \to Golgi \to secretory vesicle \to environment
B. rER \to secretory vesicle \to Golgi \to environment
C. rER \to Golgi \to sER \to cytoplasm \to environment
D. cytoplasm \to rER \to Golgi \to secretory vesicle \to environment
E. rER \to Golgi \to secretory vesicle \to environment

E. rER \to Golgi \to secretory vesicle \to environment

Explanation:

A protein that is normally localized in the cytoplasm has been engineered so that it will be secreted from the cell instead will follow the following sequence:

Rough endoplasmic reticulum (RER) (where the protien is being snthesized)> Golgi apparatus (where the sorting and packaging of the protien occurs)> Secretory vesicles> Environment.

Hence E. rER \to Golgi \to secretory vesicle \to environment is the right answer.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
