Question

Question 86 Eukaryotic cells are able to trigger the release of material from secretary vesicles (Regulated exocytosis) to the extracellular space using a process called exocytosis. An example of materials commonly released by this way is Ahormones nucleic acids sugars D. cytosoli proteins

Answer 1

86. Answer: Option A is correct
Explanation:
Nucleic acids are not secreted by cells.
Sugars are an energy source for the cell. They are not secreted by the endosymbiotic pathway.
Cytosolic proteins do not get secreted.

Peptide hormones are synthesized on ribosomes located on the RER. The nascent peptide enters the ER lumen for modifications and subsequently enters the cis-face of the Golgi complex. It further undergoes post-translational modifications in the Golgi and gets released as small vesicles that fuse with the plasma membrane and get secreted into the extracellular space. This pathway is known as the secretory-vesicular pathway.
