O Signal Recognition Particle (SRP) O SRP Receptor O Translocon O Ribosome QUESTION 9 1 points Save Answer Molecules taken into the cell by receptor-mediated endocytosis usually end up where in the cell? O Lysosome O Endoplasmic reticulum O Golgi apparatus ONucleusExplanation / Answer
5) The correct option is A set of an amino acids within a nuclear protein that allow the protein to enter the nucleus from the cytoplasm.
A nuclear localization signal is an amino acid sequence, which 'tags' a protein for import into the cell nucleus by nuclear transport.
6) The correct option is ER- Golgi-plasma membrane.
Proteins destined to be secreted move through the secretory pathway in the following order: rough ER ER-to-Golgi transport vesicles Golgi cisternae secretory or transport vesicles plasma membrane through the process of exocytosis.
7) The correct option is ER, Golgi, Lysosomes and Endosomes.
The endomembrane system include the endoplasmic reticulum,the Golgi apparatus, lysosomes, vesicles, endosomes and the cell membrane.
8) The correct option is Signal recognition particle(SRP).
It is sequence of hydrophobic amino acids and ER signal sequence. It is recognized and bound by a signal-recognition particle (SRP) on the rough ER membrane.
