The pancreas plays a critical role in __________.a. the absorption of nutrients
b. the digestion of vitamins
c. the elimination of enzymes
d. the breakdown of carbohydrates

Answers

The pancreas plays a critical role in the break down of carbohydrates. The pancreas is an organ located in the abdomen. it plays an essential role in converting the food we eat into fuel for the body's cells. The pancreas has two main functions: exocrine function that helps in digestion and an endocrine function that regulates blood sugar. Enzymes, or digestive juices, are secreted by the pancreas into small intestine. The pancreas also produces also produces the hormone insulin and secretes it into the bloodstream, where it regulates the body's glucose or sugar level.

The pancreas plays a critical role in the breakdown of carbohydrates. Therefore, option (D) is correct.

Carbohydratebreakdown requires the pancreas. Behind the stomach is a crucial organ. It produces and secretes digestive enzymes, including amylase, which breaks down carbs into sugars. Carbohydrate breakdown is vital for nutrition intake and energy production.

The pancreas releases amylase into the small intestine after eating carbs. Amylase hydrolyzes complex carbohydrates like starches into glucose. Simple sugars are easily absorbed into the bloodstream and delivered to cells for energy production.

Carbohydrate malabsorption, malnutrition, weight loss, and blood sugar abnormalities can result from pancreatic amylase malfunction. Therefore, option (D) is correct..
