Answer 1

Hint: To answer this question, you should recall the concept of artificial sweeteners. Artificial sweeteners are substances that are used as substitutes for natural sugar (sucrose), they contain low calories. They are repeatedly sweeter than regular sugar so that they also are mentioned as intense sweeteners


Complete Step by step solution:
You should know that artificial sweeteners are defined as the food additives which serve the purpose of providing a sweet taste but at the same time containing significantly less amount of food energy than the first sugar-based sweeteners, making it a non-nutritive sweetener. This feature of zero calories makes them effective for weight loss. This reduces overall calorie consumption as they are not metabolized in the body and straightforward excreted out of the body. This in turn, helps maintain a healthy weight and thereby lowering the danger of heart condition and diabetes.
An example includes saccharine and its salts which are lifesavers for countless diabetics and are of great value to people that get to control the intake of calories.
Thus, both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Therefore, we can conclude that the correct answer to this question is option A.


Note: For a sweetening agent to work properly, a sweetener should be soluble in water and it should readily bind with a receptor molecule present on the surface of the tongue. The receptor is connected with a G- protein and when the sweetener binds with the receptor, the G- protein starts dissociating which in turn activates a nearby enzyme and triggers a sequence of events in which the signals are transmitted to and are interpreted by the brain. The interaction between the receptor and sweetener accounts for the sweetness of a man-made sweetening agent.
