Insulin is a protein that is produced by certain pancreatic cells and secreted into the bloodstream. (This is true.) Which of the following choices best describes the route of insulin from its production to its exit from the cell ? A. contain membrane folds called cristae, whereas chloroplasts contain disk-like vesicles in stacks called grana. B. rough ER, transport vesicles, Golgi apparatus, transport vesicles, cell membrane

Answers

Answer:

. B. rough ER, transport vesicles, Golgi apparatus, transport vesicles, cell membrane

Explanation:

This route follows the normal pathways any synthesised protein follows during steps of protein synthesis of cells.

1. Because Insulin is a peptide hormone needed out side the cells, it is synthesized by ribosomes attached to the Rough Endoplasmic Reticulum of the beta cells in the pancreas.The stimulus for secretions are elevated plasma concentration of blood sugar and amino acids. The protein arrives to the R.ER as preproinsulin after translation, and with the addition of disulphide bridges in the R.ER formed prosinsulin.

2.The proinsulin are transported through the transport vesicles which makes use of the cytoskeleton of the cytosol for movements to reach the Cisternae ( golgi apparatus).

3. The Golgi bodies packaged and modified the proinsulin to form active insulin. and transported these by Cisternae migration to trans-golgi reticulum.

From here they are transported to the trans-Golgi network; where they are moved into the secretory vesicles and transport vesicles.

The transport vesicles fused with the plasma membrane , and based on metabolic or vagus stimulation is secreted to the blood stream through Exocytosis.

Final answer:

Insulin is produced in beta cells of the pancreas and travels from the rough endoplasmic reticulum to the Golgi apparatus before being released into the bloodstream. Option B is correct.

Explanation:

The route of insulin from its production to its exit from the cell involves several steps. Insulin is produced by beta cells in the pancreas. It is then transported from the rough endoplasmic reticulum (ER) to the Golgi apparatus via transport vesicles. Within the Golgi apparatus, insulin is further modified and packaged into vesicles that bud from the trans face of the Golgi. These vesicles then fuse with the cell membrane, allowing insulin to be released into the bloodstream.

How are metamorphic rocks part of the rock cycle?

Answers

The term "metamorphic" means "to change form." Changes in the temperature and pressure conditions cause the minerals in the rock to become unstable so they either reorient themselves into layers (foliation) or recrystallize into larger crystals, all without undergoing melting.
