Answer:
Green house gases are the type of gases present in the air which have the ability to trap heat of the earth's surface. Gases like carbon dioxide and methane are found naturally and are known to play an important role in earth's climate. If they are not found the earth' s climate would be too cold creating problem for survival of life on the earth.
These green house gases absorb the emit the radiation in the thermal infrared range. These gases act like a blanket and save earth surface from infrared radiation by absorbing them and prevent them from escaping out of the earth surface.
But now a days due to increased in the concentration of green house gases like carbon dioxide and methane due to pollution and deforestation causing a great problem called as green house effect which lead to global warming and it a great concern for all the people now a days.
Greenhouse gases refer to the gases, which are crucial to maintaining a suitable temperature for life on Earth. Examples are methane, carbon dioxide, and nitrous oxide.
Greenhouse gases such as water vapor, methane, fluorinated gases, and carbon dioxide trap the sunlight and raise the temperature of the Earth keeping it warm.
The gases are a concern for the environment and life on earth as in the absence of these gases, the Earth's climate will be extremely cold and chilly.
These gases act as a protective blanket, saving them from infrared rays and other harmful rays. Also, the increased emission of these gases is leading to global warming, which is one of the major threats to life on Earth.
Thus, greenhouse gases are essential but their increased emission is a major concern for the planet.

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.
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.
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.
