Answer:
The positive control is control when there is an activator present which acts as a regulatory protein so the operon and activator binds and initiates the stimulation of transcription to express the gene. In absence of this activator or regulatory protein, the operon will be inactivated.
External environmental stimuli can lead to alteration of the positive control in prokaryotes such as excess lactose in the environment. These environmental stimuli can induce transcription in prokaryotes.
In this example, if glucose is not available in the environment, the transcription of the lac operon will be induced by the presence of lactose in the environment.
Glucose is a carbohydrate<span>, and is the most important simple </span>sugar<span> in human metabolism. Glucose is called a simple sugar because it is one of the smallest units which has the characteristics of this class of carbohydrates. Glucose is also sometimes called dextrose. Corn syrup is primarily glucose. </span><span>Sugars are digested and absorbed to provide your body with its greatest source of energy. During digestion, complex sugars are broken down and absorbed into the bloodstream. The simplest sugars, include glucose, galactose and fructose. Digestion occurs in the mouth, stomach and intestine.</span>
