Biology notes for class 11 Gastrointestinal Hormones

Biology notes for class 11 Gastrointestinal Hormones

In the following article, we will discuss ‘Gastrointestinal Hormones’ from Human Physiology of Biology Class 11.
Biology class 11 Gastrointestinal Hormones: The food that we ingest is broken down into simple and soluble forms by our digestive system/ alimentary canal/ gastro intestinal tract. This simple and soluble food material is absorbed into the blood stream. Through the blood, the food material is taken up by the various cells of our body and gives energy. Gastrointestinal System can be understood as a system of cells, tissues, organs, and biochemical molecules that help in digestion and absorption of food into the body. GI hormones are chemical messengers that are implicated in many aspects of physiological functions of the gastrointestinal tract, including the regulation of secretion, absorption and digestion, and gut motility. GI hormones are a large family of peptides and are secreted by endocrine cells that are widely distributed throughout the GI mucosa and pancreas. Gastrin, secretin, and cholecystokinin (CCK) were the first discovered gut hormones, and as of today, there are more than 50 gut hormone genes and a multitude of bioactive peptides, hence the gut is considered as the largest endocrine organ of the body.
The Gastrointestinal Hormones (GI or gut hormones) constitute a group of hormones secreted by entero -endocrine cells(cells that secrete their chemicals through ducts) in the stomach, pancreas, and small intestine that control various functions of the digestive organs.
Ten major known GI Hormones are enlisted here; however, new hormones are also being discovered.
  1. Cholecystokinin Pancre­ozymin
  2. Duocrinin
  3. Enterocrinin
  4. Enterogastrone
  5. Gastrin
  6. Pancreatic Polypeptide.
  7. Secretin
  8. Somatostatin
  9. Vasoactive Intestinal Peptide
  10. Villikinin

PURCHASED GOODWILL METHOD UNDER IND AS 103

The acquisition of subsidiaries results in  Goodwill calculation  and also records net assets of the subsidiary at fair value on the date of acquisition. Let’s get answers to all the questions related to Goodwill, valuation of NCI, and impairment relating to them. Q1 – What are the ways in which an entity can make payment for purchase consideration? ANS: – Cash – Share exchange – Deferred payment – Contingent consideration Q2 – How is deferred payment dealt, when it forms part of purchase consideration? ANS:  The deferred payment is discounted to present value and included in the cost of consideration. At the end of each year, the liability is increased by unwinding the discount, until the payment is settled. For example, An amount of Rs. 108,000 was deferred to be paid after 2 years. The discount rate applicable is 8%. The net present value today of Rs. 108,000 is equal to (108,000 * 1) / (1.08) ^2)= Rs. 92,593 included in purchase consideration. A liability of Rs. 92,59...
