• In secretory cells, such as the secretory cells of endocrine glands, organelles related to the production, processing and “export” of substances are widely present and well-developed. These organelles are the rough endoplasmic reticulum and the Golgi apparatus. The nuclear membrane of secretory cells generally has more pores to allow the intense traffic of molecules related to protein synthesis between the cytoplasm and the nucleus. •The opposite word is "exocrine", which means secreting through a duct or tube. Some hormones are produced by exocrine glands, and some exocrine secretions release outside the body. Sweat glands and salivary glands are examples of exocrine glands whose products are released outside the body. The first discovery of a hormone was made in 1902. •Endoplasmic Reticulum Organelle consisting of network of fluid-filled tubules and flattened sacs. Synthesis of proteins and lipids for formation of new cell membrane and other cellular components. Manufactures products of secretion.

    This cytoplasmic organelle is associated with chemical processing and the modification of proteins made by the cell as well as with the storage and marking of these proteins for later use or secretion. Vesicles seen under an electronic microscope contain materials already processed, and which are ready to be exported (secreted) by the cell.

  • Define organelle. organelle synonyms, organelle pronunciation, organelle translation, English dictionary definition of organelle. n. A differentiated structure within a cell, such as a mitochondrion, vacuole, or chloroplast, that performs a specific function. •The plant secretory pathway has a central role in the biosynthesis and secretion of proteins and cell wall polysaccharides. The first organelle in the secretory pathway is the endoplasmic reticulum (ER). Secretory proteins are generally co-translationally synthesized and inserted into the ER lumen where they are often N -glycosylated.

    The opposite word is "exocrine", which means secreting through a duct or tube. Some hormones are produced by exocrine glands, and some exocrine secretions release outside the body. Sweat glands and salivary glands are examples of exocrine glands whose products are released outside the body. The first discovery of a hormone was made in 1902.

Protein PTMs can also be reversible depending on the nature of the modification. For example, kinases phosphorylate proteins at specific amino acid side chains, which is a common method of catalytic activation or inactivation. Conversely, phosphatases hydrolyze the phosphate group to remove it from the protein and reverse the biological activity.
