Answer:
A) within the lumen of the small intestine.
Explanation:
The pancreas produces a variety of hormone-like amylase, proteases, lipases which can digest the food material.
The proteases like chymotrypsinogen and trypsinogen are produced by the pancreas in their inactive form as if active will digest the organ itself. Therefore these zymogens are stored in the secretory vesicles which release the enzymes in the pancreatic duct.
These zymogens are not activated until they reach the digestive tract that is when these enzymes enter the lumen of the small intestine, the enterokinase present there catalyzes the trypsinogen to trypsin. Trypsin converts the chymotrypsinogen to the chymotrypsin.
Thus, Option-A is the correct answer.
During asexual reproduction
Answer:
diverse proteins embedded in a phospholipid bilayer
Explanation:
According to fluid mosaic model the cell membrane is made of bilayer of phospholipid. Many proteins are embedded in this bi layer. Carbohydrate and cholesterol are also found in different forms. Carbohydrate can either be attached to the embedded protein in which case it is called as glycoprotein or it can be connected to the lipid molecule in layer and called as glycolipid.
Proteins can be found in two forms too. They can either be embedded in the layer i.e. they can penetrate single or both layers. These proteins are called as integral proteins. They can also be present on one side of the membrane and not penetrate the lipid bilayer in which case they are called as peripheral proteins.
