Arrange the steps of the formation of a secretory protein from its gene to its exocytosis. RNA polymerase binds to the promoter region of a gene encoding a secretory protein. Exocytosis from the cell. Answer Bank The protein is sequestered into transport vesicles and sent to the Golgi complex. The RNA is translated into protein by ribosomes on the endoplasmic reticulum. The protein enters the lumen of the endoplasmic reticulum. The gene undergoes transcription. The protein is packaged into secretory vesicles.

Q: Distinguish among phagocytosis, pinocytosis, receptor-mediated endocytosis, and exocytosis.

A: The cell membrane is thin, elastic, and has a flexible covering that holds the cellular contents. It…

Q: describe in detail the pathway of lysosomal enzyme from the endoplasmic reticulum to the lysosome

A: Lysosomes are tiny vesicles with hydrolytic enzymes that are separated by a single membrane. Because…

Q: Why doesn’t the cell “clean up” the faulty lysosomes?

A: Lysosome is membrane bound organelle which encloses enzyme responsible for the breakdown of complex…

Q: Compare and contrast lysosomes with peroxisomes:name at least two similarities and one difference
