A patient has an under-functioning pancreas, which of the following will NOT be affected?
A) Enzyme function in the small intestine. B) Polypeptide digestion. C) Na+/K+ pump activity on the microvilli. D) Breakdown of energy stores in response to fasting.
option C is correct
A.. enzymes functions small intestine is affected in under functioning pancreas ....pancreas secrete juices that break down sugar s ,fats, starches...releaseed pancreatic juices travel to deodenum (upper part of small intestine ) it helps in digestion and bicorbonates to neutralize stomach acid as it is that enter the small intestine
B...polypeptide digestion are done by the secretions of pancreas that is trypsin, chymotrypsin...proteins are breakdown in the presence of trypsin,,chymotrypsin produce polypeptide....polypeptides are further breakdown into aminoacids and smaller peptides in the presence of protease ...protease is produced by pancreas, stomach, small intestine.
D..in fasting condition hunger is increased so in this situation breakdown of energy sources is done...that is stored fat...stoed fat is breakdown and produce energy to the body....
falling glucose levels it triggers the pancreas to release glucagon to turn off the glycogen synthesis in the liver and stimulates its breakdown into glucose...
if pancreas is not working properly,,breakdown of energy stores are not done .....pancreas doest not send any messages to the liver....
C..Na+/K+ activity of the microvilli is not related to the pancreas...there is no relationship between this..so this option is not be affected
