Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A cell of the pancreas produces digestive enzymes, which are proteins. The enzymes are released into the small intestine.Suggest which two of the following are adaptations to its role?Tick two boxes.
A
A small surface area to volume ratio
B
Large numbers of ribosomes
C
Mitochondria with well-developed internal membranes
D
The ability to move
Explanation: 

Detailed explanation-1: -An enzyme is a protein and protein synthesis occurs in the ribosomes of cells, particularly cells that have the role of producing enzymes for the digestion of material in the small intestines. So one adaptation would be that it has many ribosomes.

Detailed explanation-2: -Amylase. This enzyme helps break down starches into sugar, which your body can use for energy.

Detailed explanation-3: -Pancreatic acinar cells form a basic structure called an acinus that surrounds a central lumen open to the duct system. Pancreatic acinar cells produce, store and secrete enzymes necessary for the digestion and absorption of food in the small intestine.

Detailed explanation-4: -The pancreatic enzyme that is involved in the digestion of protein is trypsin. Trypsin acts on complex protein molecules and converts those into smaller peptides.

Detailed explanation-5: -Of these five components, pepsin is the principal enzyme involved in protein digestion. It breaks down proteins into smaller peptides and amino acids that can be easily absorbed in the small intestine.
