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 of the following is an adaptation to its role?
A
A small surface area to volume ratio
B
Large numbers of ribosomes
C
Lots of Mitochondria.
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: -Pancreatic adaptation represents dietary regulation of gene expression; dietary substrates alter the synthesis and mRNA levels of their respective digestive enzymes. The mechanisms whereby mRNA levels change are not understood, but they must be elucidated.

Detailed explanation-3: -Amylase. This enzyme helps break down starches into sugar, which your body can use for energy.

Detailed explanation-4: -The exocrine pancreas produces enzymes that help to digest food, particularly protein. The endocrine pancreas makes the hormone insulin, which helps to control blood sugar levels.

Detailed explanation-5: -During digestion, your pancreas makes pancreatic juices called enzymes. These enzymes break down sugars, fats, proteins, and starches. Your pancreas also helps your digestive system by making hormones. These are chemical messengers that travel through your blood.
