Open Question: Does chyme stimulates the release of digestive enzymes?

Home >All Categories > Science & Mathematics >Biology >Open QuestionErnest Bohr Ernest Bohr Member since:March 12, 2011Total points:82 (Level 1)Once the stomach has formed chyme from the food mixing with gastric juices, it goes down into the intestine where the chyme "stimulates" the release of digestive enzymes from the pancreas and bile from the liver... uh what does this mean HELP? - DIGESTIVE ENZYMES FROM PANCREAS AND LIVER.. I'm so confused, HELP WOULD BE MUCH APPRECIATED!Answer Question

The GI tract releases hormones to help regulate the digestion process. These hormones include gastrin, secretin, cholecystokinin, and grehlin, are mediated through either intracrine or autocrine mechanisms, indicating that the cells releasing these hormones are conserved structures throughout evolution. If you were to google the names of these different hormones you would understand much better.
But that would give you an explanation in words.
Then you could increase your understanding further yet by searching the same terms at youtube.
And then you could try google "[search term] animation" and by that time (if you'd paid attention) you could probably get a pretty good grade on the test.
Those website along with wikipedia and khanacademy.org is how I won a scholarship to ucla. And I aint even smart, but I am devoted. But hell if i can do it than i know you can too. best of luckMiss Fab by Miss Fab Member since:September 02, 2010Total points:513 (Level 2)the pancreatic juice and bile..released from pancreas and bile respectively, works the best on chyme. the released enzymes mix quite efficiently with food in this form (chyme)

Open Question: Does this absorb or release energy?

Open Question: Does this absorb or release energy?

An iron nail (Fe) is placed into a solution of copper(II) sulfate (CuSO4). After some time, the blue color of the copper(II) sulfate disappears and some copper-colored solid (Cu) is found on the surface of the nail. The solution now contains iron(II) sulfate (FeSO4), and the container feels warmer than before the reaction.

Does this reaction absorb or release energy? How do you know?

What do the color changes indicate?

Thanks for the help! i think it releases energy, but i dont know why other then the container gets warmer. Thanks again!!
