Answer:

TRUE

Explanation:

Endemic diseases are the diseases or infections that are persistently present in the population of a particular geographical area.

An endemic infection or disease does not increase at an exponential rate and also does not get eliminated entirely. Therefore, such an infection is constantly maintained without any external outputs and thus reaches the endemic steady state.

What is the route of non-fat nutrients from the small intestine to their release as nutrients to the body?

miv72 [106K]

The route of non-fat nutrients from the small intestine to their release as nutrients to the body can vary depending upon the type of nutrient. They can be transported either by passive or active transporters, or through blood stream, or may be absorbed by water.

Small intestine is a part of the digestive system. Its function is to digest the various food components, specially fats and proteins. Small intestine is a very large tube-like structure that is fit compactly surrounded by the large intestine.

Nutrients are components present inside food that are required for the growth and strength of the body, They provide several benefits like body-building capacity, immunity from diseases, proper functioning, etc.

What is the biochemical explanation for why adding glucose to a bacterial culture containing lactose significantly decreases pro

MatroZZZ [7]

Answer:

If we add glucose to the culture with lactose, the lac operon would be turned off and the production of beta-galactosidase, other enzymes and molecules that the operon transcribes, would decrease.

On the contrary, if we add lactose to a bacterial culture containing glucose, the lac operon would be on, transcribing the genes, hence, producing beta-galactosidase but only at a small rate. Because the bacteria already got the energy from the glucose.

Explanation:

An operon is a group of structural genes whose expression is regulated by a promoter, operator and regulator genes. In this particular case, they are talking about the lactose operon, lac operon. This operon is required, in bacteria, to obtain energy from lactose when there is no glucose present.

The lac operon contains a series of genes, lacZ, lacY, and lacA. The gene LacZ codifies an enzyme required to break the lactose, beta-galactosidase. LacY codifies for another enzyme required in the transport of lactose inward the cell. And finally, LacA produces a molecule that is involved in detoxification.

The lac operon is regulated, among others, by the presence of glucose and lactose. The glucose is the preferable source of energy for bacteria so if there are lactose and glucose the glucose would be used for energy at a bigger extent. In the absence of glucose, the lac operon plays a vital role and helps the bacteria to obtain energy from lactose.

When there is glucose but no lactose available, there is a repressor than binds to the promoter so the lac operon is OFF cannot express the genes.

On the other hand,when there is lactose and no glucose, lactose enters the cell and some of this molecules turn to alolactose. Alolactose molecules bind to the repressor so the operon is not repressed anymore and the lac operon would be ON producing enzimes and molecules.

If the lac operon is ON ( glucose absent ) the production of beta-galactosidase would be high, on the other hand, if the operon is OFF (glucose present) the production of beta-galactosidase decreases.

In the presence of both lactose and glucose, the genes for the lactose metabolisms are transcribed at low rates in the lac operon.
