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.

Which veterinary professionals design the veterinary curriculum? please help ​
Virty [35]

Answer:

Recent studies of the veterinary profession have established a need for training in various areas beyond those directed toward building competence and proficiency as a clinician.

The model curriculum was created from comprehensive input provided by consultants and educators. Constraints for implementation of this curriculum are identified, and future directions are discussed.
