which cell organelle is involved in the production of insulin?

Answer 1

The 1st 2 answerers are confused. The question isn't about organs or cells, it's about organelles, which are structures within cells.

I believe the answer you're looking for is the islet in the pancreatic cells. I found this:
"The islet is a small organelle made up of several cells types, and is found within the pancreas. Islets make up about 2% of the entire pancreas. One of the cell types in the islet is the b cell. This cell is responsible for producing all the insulin the body will need."

That's the Institute for Cellular Therapeutics at the University of Louisville.

But wait, there's more:
The mRNA (messenger RNA) moves from the nucleus to the cytoplasm via nuclear pores

A ribosome attaches to the mRNA and begins to make the protein insulin which moves into the RER (rough endoplasmic reticulum) .

Insulin is transported from RER to Golgi via a transport vesicle

That's from http://www.mc.maricopa.edu/~brown/Bio_181_lectures/bio_181_lecture_3_the_cell.htm

According to that detailed description a number of organelles are involved. Makes sense, doesn't it? We're pretty complicated chemical factories.

Answer 3

A specific cell called a beta cell found in the islets of langerhans in the pancreas produces insulin. That is the only place in the body it is produced and those are the only cells that make it. It is a protein and so it is made like all other proteins and it involves the whole cell working together to synthesize the protein. You can look up insulin or protein on www.wikipedia.org to get a better more detailed explanation.

Answer 4

yea. the first two answers are incorrect. if the question were 'where in the body is insulin produced' then beta cells of the pancreas is spot on. but you asked for the cell organelle involved.

endoplasmic reticulum is somewhat the correct answer. when the primary protein strand that codes for insulin is produced from the dna (by the process of protein biosynthesis) it goes into the endoplasmic reticulum. it is here where this simple strand gets shaped into a complex macromolecule that is now called insulin. this newly formed insulin now goes to the golgi apparatus for export out of the cell via exocytosis.

i hope you get this. : )

Answer 5

Produces Insulin

Answer 6

When cells manufacture a protein that is released to the outside, that protein is made in a slightly different way than proteins that are used within the cell. Ribosomes are the functional mechanism that assemble peptide chains (protein structures). Ribosomes that manufacture proteins that are RELEASED from cells are located along the ROUGH ENDOPLASMIC RETICULUM. Ribosomes that make proteins used within the cell itself are located free within the cytoplasm.

Insulin is a protein that is manufactured and then released from the beta cells located in the islets of langerhans (microscopic endocrine organs located within the pancreas). These cells are rich in rough E.R., and the pro-insulin molecule is manufactured there. After manufacture, there is one remaining step before the insulin is active. A "C-peptide" is cleaved off from pro-insulin, yielding the active form.

Answer 7

the pancreas is an organ, not an organelle. Insulin would be made like any other hormone. It's transcribed and then translated, and then the endoplasmic reticulum is involved with folding and export, the golgi apparatus packages and modifies it.

Answer 8

Insulin is a hormone that is produced by specialized cells (beta cells) in the pancreas

Answer 9

beta cells in the pancreas

Answer 10

THEY ARE PRODUCED BY THE BETA CELLS OF THE ISLETS OF LANGERHAUS IN THE PANCREAS.
