Which would not be found in pancreatic juice secreted into the duodenum?
AURORKA [14]

Answer:

The answer is insulin.

Explanation:

Pancreatic juice is an enzyme containing secretion produced by the pancreas into the small intestine. Enzymes in the pancreas help in digesting proteins, carbohydrates and fats. The constituent enzymes are as follows:

  1. Trypsinogen and Chymotrypsinogen: Precursors of the proteases, trypsin and chymotrypsin that digest proteins. They are released as precursors to protect the intestinal lining. Enterokinase, an enzyme secreted by small intestine's epithelial cells, activates these precursor.
  2. Lipase: Enzyme that digests lipids by hydrolysing triglycerides into 2-monoglyceride and two free fatty acids.
  3. Amylase that helps in digesting any left over carbohydrates and complex starch.

Insulin:

Insulin can never be part of pancreatic juice because it is a hormone, not an enzyme. Hormones are chemical messengers secreted only in blood. Insulin is a hormone secreted by the pancreas to lower blood glucose levels by binding to insulin receptors on cells and stimulating the intake of glucose through glucose transport channels (GLUTs) in the cell membrane.

There are no genetics that can save you from constant overeating and there are no genetics that can prevent you from working out, at least to your possible extent.</span>
