Background and Aims: An agonist produces a physiological response upon binding to a receptor while an antagonist inhibits agonist-mediated responses. It is reported that muscarinic acetylcholine receptors‚ located on the ileum of the small intestine‚ initiate contractile activity when an agonist (acetylcholine) is present. The purpose of this study was to examine the effects of a competitive antagonist (atropine) on the muscarinic acetylcholine receptors. Methods: The isolated guinea pig ileum

He was speaking of the potato‚ and its ability to adapt to a variety of climates‚ from the semiarid to the tropical wet. Potatoes also have high nutritional value. They supply every vitamin and mineral that a body needs except for vitamin A‚ vitamin

Potatoes use the acids within them to start a reaction between the copper and zinc wires on either side of it. This reaction causes the flow of electrons passing through the wires and using the positive and negatively charged electrons to power the

Property of Starch The experiment obtained Starch to have a bulk density of 0.48g/ml‚ i.e. 0.48g of Starch occupies 1ml of water. This value represented the density of starch incorporating the voids. The tapped density was found to be 0.60g/ml. This value represented the density of starch excluding the voids and intra- particle pores greater than molecular and atomic dimensions in the crystal lattice. This simple means‚ by reducing the number of intermolecular spaces between the starch particles‚
