The polypeptide encoded by the glucose carrier gene has a signal sequence. As a result, the ribosome and the polypeptide that is
beginning to be made will be transported to the _________ (a cellular compartment) where translation will continue. Then the newly made glucose carrier protein will travel through ______________ (another cellular compartment), and then finally be sent to the plasma membrane. Once there, it will allow glucose to enter the cell through _________________ (simple diffusion, facilitated diffusion or active transport).
During the translation stage of protein synthesis, signal sequences are either attached or excluded from a synthesized protein in order to indicate the right location it should be sent to. Proteins that possess signal sequences are usually sent to the endoplasmic reticulum, where they will be folded into their right shapes. From the endoplasmic reticulum the proteins are then transported into Golgi apparatus via membrane vesicles. In the Golgi apparatus, proteins undergo their final modifications before they are transported to their final destinations. The final destination of glucose carrier proteins is the plasma membrane, where they help glucose molecules to enter the cell via facilitated diffusion.
If people are evacuating, the owner of the gas station isn't there to lower the price, and even then, they would only improve the price, so they can get more money, just like when you need to get water at a store for a hurricane, they DON'T LOWER IT!!!
