Which of the following is involved in the processing and packaging of certain molecules produced for secretion by a cell?

Which of the following is involved in the processing and packaging of certain molecules produced for secretion by a cell?

The Golgi apparatus, or Golgi complex, functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations: lysosomes, the plasma membrane, or secretion. In addition, as noted earlier, glycolipids and sphingomyelin are synthesized within the Golgi.

Which organelles are involved in the synthesis and secretion of insulin?

It is the endoplasmic reticulum and the ribosomes of the specialized cells in the pancreas that make insulin. Remember, most human cells make proteins at the protein factory called the ribosome. This ribosome is either free floating in the cytoplasm, or is attached to the endoplasmic reticulum.

Which part of the cell is responsible for packaging substances made in the cell?

The Golgi apparatus
The Golgi apparatus is a set of flattened, membrane-bound sacs that serve as the packaging and distribution center of the cell.

Which is responsible for storage alteration and packaging of secretory products and lysosomal enzymes?

The Golgi apparatus (/ˈɡɒldʒi/), also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells.

What type of endoplasmic reticulum is involved in protein synthesis?

rough endoplasmic reticulum
rough endoplasmic reticulum (RER), series of connected flattened sacs, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that plays a central role in the synthesis of proteins.

What organelle would be responsible for the packaging and transporting the insulin out of the cell?

In specialist secretory cells the Golgi complex is responsible for the sorting and packing of such well-known items as insulin, digestive enzymes and pectin. The Golgi apparatus produces specialist vesicles or vessels for the transport of its products.

How is insulin modified packaged and secreted by the cell?

Insulin and free C peptide are packaged in the Golgi into secretory granules which accumulate in the cytoplasm. When the beta cell is appropriately stimulated, insulin is secreted from the cell by exocytosis and diffuses into islet capillary blood.

What part of the cell is involved in locomotion and transport of vesicles or cargo within?

The Golgi apparatus is the central organelle mediating protein and lipid transport within the eukaryotic cell.

Where are cell products modified and packaged in vesicles for transport?

The Golgi apparatus is responsible for transporting, modifying, and packaging proteins and lipids into vesicles for delivery to targeted destinations.

Which structure is responsible for the synthesis and assembly of ribosomes?

nucleus
The nucleus (plural, nuclei) houses the cell’s genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins. Inside the nucleus, chromatin (DNA wrapped around proteins, described further below) is stored in a gel-like substance called nucleoplasm.

What functions in the synthesis of secretory products as well as intracellular storage and transport?

Endoplasmic reticulum — an extensive network of membrane-like channels that extends throughout the cytoplasm; it synthesizes secretory products and is responsible for intracellular storage and transport.

How are proteins synthesized in the cell membrane?

In the cytoplasm the protein polymers are actually “synthesized” through chemical reactions – that is why the process is known as “protein synthesis” or even more precisely – “protein biosynthesis”. The RNA copy of the protein genetic information encoded in DNA molecule is produced in the nucleus and it is called messenger RNA (mRNA).

What is the role of DNA in protein synthesis?

Protein synthesis is one of the most fundamental biological processes by which individual cells build their specific proteins. Within the process are involved both DNA (deoxyribonucleic acid) and different in their function ribonucleic acids (RNA).

How are proteins made in the public domain?

( “Protein” by National Cancer Institute is in the Public Domain) The information to produce a protein is encoded in the cell’s DNA. When a protein is produced, a copy of the DNA is made (called mRNA) and this copy is transported to a ribosome.

Where does the protein go when it is made?

If the protein is going to be used within the cytoplasm of the cell, the ribosome creating the protein will be free-floating in the cytoplasm.
