If lactose levels are low in the body, it typically means that there is a reduced ability to digest lactose, a sugar found in milk and dairy products. This condition is often due to low levels of lactase, the enzyme responsible for breaking down lactose. As a result, individuals may experience symptoms like bloating, gas, diarrhea, and abdominal pain after consuming lactose-containing foods. In such cases, individuals might need to limit their intake of dairy or consider lactose-free alternatives.

When is lac operon most active?
The lac operon is most active when glucose levels are low and lactose is present.
The lac operon enables a bacterium to build the proteins needed for lactose metabolism only when?
Lactose is present, otherwise the lac operon is not needed and is shut off.
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.
When does the induction of the lac operon occur?
The induction of the lac operon occurs when lactose is present in the environment and glucose is limited. The presence of lactose leads to the activation of the lac repressor protein, allowing RNA polymerase to bind to the promoter region and transcribe the genes involved in lactose metabolism.
What normally happens to the levels of lactase produced throughout a persons lifetime?
Lactase production typically declines after weaning, as many individuals lose the ability to digest lactose in adulthood. This decrease varies among populations, with some maintaining higher lactase levels due to genetic adaptations linked to dairy consumption. In lactose-intolerant individuals, lactase levels drop significantly, leading to difficulties in digesting lactose found in dairy products. Conversely, those with lactase persistence continue to produce the enzyme into adulthood, allowing them to digest lactose without issues.
Does cottage cheese affect lactose intolerant people?
Cottage cheese can affect lactose-intolerant individuals differently, depending on the severity of their intolerance. While it does contain lactose, many brands offer low-lactose or lactose-free options. Additionally, the fermentation process involved in making cottage cheese reduces lactose levels, making it more tolerable for some people. However, those with severe lactose intolerance may still experience discomfort, so it's best for them to consult with a healthcare professional.
What does lactose do?
Firstly, I think you phrased this question wrong because lactose is a substrate. It is the job of lactase (and enzyme) to break down lactose. Some people are lactose intolerant because their bodies do not have enough lactase enzymes to break down lactose.
What happens when milk is treated with lactase?
Lactase is an enzyme that breaks down lactose in milk. This allows lactose intolerant individuals to drink the lactose free (or reduced lactose) milk.
What typically happens to the inflation rate when unemployment falls to very low levels?
it rises
What happens to enzymes at low pH levels?
At low pH levels, enzymes can become denatured, meaning their structure and function can be disrupted. This can lead to a decrease in enzyme activity and effectiveness.
How does your electrolyte balance get affected and what happens when the levels are too low?

What happens when lactose isn't presrnt?
You have black coffee.
