If there is no lactose present, how does bacteria respond? The gene for beta-galactosidase turns on. The gene for beta-galactosi

mojhsa [17]

Answer:

The gene for beta-galactosidase turns off.

Explanation:

The gene that codifies the beta-galactosidase enzyme is part of the <em>lac</em> operon, which also contains two other genes that produce enzymes involved in the metabolization of lactose.

Between glucose and lactose, the bacteria will preferentially use glucose as an energy source. On the other hand, lactose is a dimer, and thus a series of enzymes are needed to process lactose before its use as an energy source.

If there is no lactose present, the genes contained inside this operon are turned off (the operon is repressed).

Use exacly 100 letter to write a sentence about what the world willbe like in 100 years

Doss [256]

Borders are still guarded zealously and fought for - via wars when required and when not required in equal measure. I see nations fighting
over water that preciously scarce resource of the future. I see that terrorists still abound - the Osama Bin Laden types still roam the Earth terrorizing countries and peoples with newer weapons and newer methods of instilling terror. I see that the United States is no longer the sole superpower of the world -- the most powerful country on Earth. I see the most powerful countries dominating the world as being China, India, Brazil and Russia in that order. I see that China and India have become the equivalent of the US and the erstwhile Soviet Union - fighting another Cold War between them and competing for resources and influence around the world.

Based on the information provided, what do you think the most ideal parameters would be for optimal glucose production?

Marysya12 [62]

The most ideal parameters for optimal glucose production are insulin sensitivity SI, glucose effectiveness SG, insulin action p2 and the volume of distribution of glucose V.

<h3>What is used for glucose production?</h3>

Insulin, glucagon, and hepatocyte-derived factors are used in these activities. Gut: Hormones are released in the gut in response to nutrition intake. These hormones affect hunger, stomach emptying, glucose production, and glucose elimination.

After eating, the beta cells release insulin into the bloodstream as your blood glucose levels rise. In order for glucose to enter muscle, fat, and liver cells, insulin works as a key to unlocking those cells. The majority of the cells in your body use glucose, lipids, and amino acids (the components of protein) as fuel.

By converting glycogen into glucose, a process known as glycogenolysis, the liver produces sugar or glucose. Additionally, the liver may produce the sugar or glucose that is required by harvesting amino acids, waste, and fat.
