Question

1. a ribosome synthesizes insulin and it moves inside an er tube or sac; 2. a group of insulin molecules gets moved through a tube that extends from the er to the golgi; 3. insulin molecules are moved through the stack of golgi sacs in sequence and enter a vesicle; 4. motor proteins walk vesicles filled with insulin to the cell membrane; 5. the vesicle membrane fuses with the cell membrane and dumps the signals into your bloodstream. a quick note about the endomembrane system: insulin is an example of a secreted protein, meaning it is packaged and eventually leaves the cell that made it. the endomembrane system also processes proteins that are embedded in membranes throughout the cell, such as transmembrane proteins in the plasma membrane. this readiness reading will focus on secreted proteins like insulin and saves the details of membrane - bound protein processing for a more advanced biology course. how does all this happen? read on! \based on what ive learned about cells thus far, getting insulin molecules from a ribosome through the system and into the bloodstream is probably totally random.\ true false

Explanation:

Insulin synthesis and secretion involve a series of highly - regulated steps within the endomembrane system. It starts with ribosome - based synthesis, followed by transport through the ER, Golgi, and vesicles guided by motor proteins. This is an orderly process, not random.

Answer:

False
