What else can I help you with?
The obvious advantage of the lactose operon system is that?
it allows bacteria to regulate the expression of genes involved in lactose metabolism in response to lactose availability. This enables efficient utilization of lactose as an energy source only when needed, conserving cellular resources when lactose is not present in the environment.
Why enzymes are necessary for biological process?
Enzymes are proteins which act as catalysts and allow complex chemical reactions to occur rapidly. Without enzymes, reactions would not occur quickly enough to allow cells to function effectively. For example, people who are lactose intolerant do not produce enough of the enzymes which break down lactose and therefore cannot digest lactose properly.Sources:Biology courseBrain, Marshall.

What organ releases sucrose maltose and lactose to break down sucrose?
The organ that releases enzymes to break down sucrose, maltose, and lactose is the pancreas. It secretes digestive enzymes, including maltase and sucrase, which help in the breakdown of these sugars in the small intestine. Additionally, the small intestine itself also produces enzymes that further assist in carbohydrate digestion.
Where does Lactose metabolism occur in the human body?
Lactose metabolism primarily occurs in the small intestine. Enzymes called lactase are responsible for breaking down lactose into its simpler forms, glucose and galactose, which can then be absorbed by the body for energy. If lactase is deficient, individuals may experience lactose intolerance.
What enzyme act on Lactose?
The enzyme that acts on lactose is called lactase. Lactase breaks down lactose into its component sugars, glucose and galactose, which can then be absorbed by the body. People who are lactose intolerant have low levels of lactase, leading to difficulty digesting lactose.
What are digestive enzymes related to lactose?
Lactase.Lactase is essential for digestive hydrolysis of lactose in milk. Deficiency of the enzyme causes lactose intolerance.
Does citrobacteria ferment lactose?
Yes, Citrobacter species are capable of fermenting lactose. They possess the necessary enzymes to break down lactose into glucose and galactose, allowing them to use lactose as a source of energy.
Describe the effect a repressor has on the lac operon when lactose is present?
When lactose is present, it binds to the repressor protein, causing a conformational change that prevents the repressor from binding to the operator region of the lac operon. As a result, RNA polymerase can transcribe the structural genes of the lac operon, leading to the production of enzymes involved in lactose metabolism.

If a person is lactose intolerant their body cant absorb what?
Their body can't absorb lactose...There are enzymes in your small intestine which break down lactose called lactase. Lactase breaks down lactose into galactose and glucose so your body can then absorb it.
What makes some people lactose intolerant as adults?
Some people don't produce any enzymes, including the one needed to digest lactose
Why does sucrase not hydrolyse lactose?
"because the reaction is to slow to make an effect, if a enzyme is added then it can hydrolyse lactose but it can take more than 6 years without the addition of an enzyme" Is bull**** the real answer is because the active site of the two substances are different and so the sucrase becasue Lactose has a different shape/structure which does not fit/bind to active site of enzyme/sucrase.
What effect does enzymes have on the cholesterol?
It has no effect
What happens to the lac operon when lactose is absent?
When lactose is absent, the lac operon is typically turned off or repressed. This means that the genes involved in lactose metabolism are not actively transcribed and the production of the necessary enzymes is halted.

Enzymes are often bigger than the chamicals they bind to They also have a specific shape How do these facts help explain the way enzymes work?
The shape of the enzyme allows it to only accept certain substrates. For example, if you are lactose intolerable you cannot have lactose (a sugar) due to the fact that you do not have lactase (an enzyme) to break the lactose down. Enzymes, themselves, do not, split chemicals the split organic substrates such as carbohydrates, lipids (fats) and proteins.
Why doesnt the lactase in lactose intolerant people work?
Lactose intolerant people have a deficiency of an enzyme called lactase, which breaks up the lactose into two monosaccharides called galactose and glucose. These two are easily digestable, whereas lactose is not.
