Question

What is Gluconeogenesis .?
And write short note on :
1) Gastrin
2) Inhibin
3) Secretin
4) ANF

Answer 1

The synthesis of glucose from noncarbohydrate precursors is called gluconeogenesis.

i hope it helps u  

Answer 2

Gluconeogenesis (abbreviated GNG) is a metabolic pathway that results in the generation of glucose from non-carbohydrate carbon substrates such as lactate, glycerol, and glucogenic amino acids. it is also the one of main mechanism that human and other main animals use from keeping the blood glucose level from dropping low.
Gluconeogenesis is a ubiquitous (present everywhere) process, present in plants, animals, fungi, bacteria, and other microorganisms. 
_______________________
Gastrin is a peptide hormone that stimulates secretion of gastric acid by the parietal cells of the stomach and aids in gastric motility. It is released by G cells in the pyloric antrum of the stomach, duodenum, and the pancreas.
________________________________
Inhibin is a protein secreted by granulosa (female) and Sertoli (male) cells in response to FSH, and its major action is the negative feedback control of pituitary FSH secretion 
___________________________________
Secretin is a hormone released into the bloodstream by the duodenum (especially in response to acidity) to stimulate secretion by the liver and pancreas.
____________________________________
ANF- Atrial natriuretic peptide (ANP), also called Atrial natriuretic factor (ANF), Atrial nartiuretic hormone (ANH), cardionatrine, cardiodilatin (CDD), or atriopeptin, is a powerful vasodilator, and a protein (polypeptide) hormone secreted by heart muscle cells.
