Explanation:
Ionotropic acetylcholine receptors are also called nicotinic acetylcholine receptors because beside acetylcholine (Ch) they respond to nicotine. These receptors are primary receptors in muscle for motor nerve-muscle communication that controls muscle contraction.
Two molecules of ACh are required for receptor to open. Since the receptors are linked to ion channels, the channels open. Opening of the channel allows positively charged ions to move across it: sodium enters the cell and potassium exits.
Answer:
An enzyme refers to a kind of protein found inside a cell. The enzymes result in the chemical reactions within the body. The function to accelerate the rate of chemical reaction in order to support life. The enzymes in the body assist in performing very essential functions. These comprise eradicating toxins, building muscle, and dissociating particles of food at the time of digestion.
Enzymes are needed for performing the proper function of the digestive system. Digestive enzymes are primarily produced in the stomach, pancreas, and small intestine. However, even salivary glands generate digestive enzymes in order to dissociate the molecules of food at the time of chewing.
There are three prime kinds of digestive enzymes, which are classified on the basis of the reactions they catalyze. These are protease, amylase, and lipase.
