Answer:
mRNA must start membrane protein in the cytoplasm and, after that, continue it in the rough ER.
Explanation:
Protein synthesis is initiated when mRNA meets a free ribosome, the primary structure for protein synthesis. Ribosomes can be found in the r<em>ough endoplasmic reticulum</em> or floating in the cytosol. They read the mRNA code and add the correct amino acid using transference RNA to build the protein.
The <u>rough endoplasmic reticulum</u> is in charge of the synthesis and transport of the membrane proteins. It is also in charge of the latest protein modifications after transduction. Synthesis of membrane proteins <u>starts in the cytoplasm</u> with the production of a molecule portion known as a signal sequence. This portion leads the synthesizing protein and associated ribosome to a specific region in the Rough endoplasmic reticulum where it continues the protein building.
Membrane proteins are synthesized in the endoplasmic reticulum and <em>sent to the Golgi complex in vesicles</em>, where it happens the final association of carbohydrates with proteins. Finally, protein is transported <em>from the Golgi complex to its final destiny, the membrane. </em>
Answer is: <span>a. True.
</span>The overall effect of insulin is to lower blood glucose and amino acid levels by promoting their cellular uptake and incorporation into glycogen and proteins, respectively. <span>The net effect of insulin is to decrease blood glucose and amino acids and stimulate the cellular uptake of these molecules and their incorporation into polymers.
</span>Insulin <span>is a </span>peptide hormone<span> produced by </span>beta cells<span> of the </span><span>pancreatic islets.</span>
There are so many examples for that in different areas, like TPT1 experiment carried out in our lab recently.Here's one link: http://www.alfa-chemistry.com/tpt1-cas-167218-46-4-item-290583.htm
