Lactase enzyme simulation answers

Promoter: This is a site for regulation of transcription. Every structural gene in eukaryotes has the promoter site which consists of several hundred nucleotide sequences that serve as the recognition point for RNA polymerase binding, located at a fixed distance from the site where transcription is initiated.
Lactose is the substrate that binds to the enzyme lactase. Define active site and explain how it relates to the lactase chemical reaction. The region of the enzyme where a substrate binds and where the chemical reaction occurs. Lactose, the substrate, binds to lactase's active site, so lactase can convert lactose into glucose and galactose.
Enzymes have active sites where the substrates bind. These active sites are damaged or in other words their shape is changed by changing the pH. Substrates no longer fit the active site and the reaction does not occur. A pH of about 7 is the optimum and as the pH moves further away from the optimum pH the enzyme activity starts to slow down.
Introduction to Enzymes The following has been excerpted from a very popular Worthington publication which was originally published in 1972 as the Manual of Clinical Enzyme Measurements. While some of the presentation may seem somewhat dated, the basic concepts are still helpful for researchers who must use enzymes but who have little ...
In normal humans, the enzyme that does so —lactase— stops being produced when the person is between two and five years old. The undigested sugars end up in the colon, where they begin to ferment, producing gas that can cause cramping, bloating, nausea, flatulence and diarrhea.
Lactase persistence (LP) is an autosomal dominant trait enabling the continued production of the enzyme lactase throughout adult life. Lactase non-persistence is the ancestral condition for humans, and indeed for all mammals [1]. Production of lactase in the gut is essential for the digestion of the milk sugar lactose.
Your answer should consider two key “facts” of the case: (1) people have more time at home and (2) people are watching more movies. (2 marks) Given your answer to part 2a above, now consider the impact on the market for popcorn. You should assume that even in the time of the pandemic, people enjoy eating popcorn while watching a movie. (1 mark)
The lactase enzyme is not affected by the acidy vinegar which might even help the lactase do its job better. Baking soda, on the other hand, is a base, and we don’t find a lot of basic substances in our digestive systems! Basic compounds like baking soda can damage enzymes like lactase, preventing them from working as well.
Sep 25, 2012 · Lactase is an enzyme that breaks down the substrate of lactose. The lactose is broken down into glucose and galactose. Once its broken down its easy to use a glucose test strip to see how much glucose is in the lactose to see how much the enzyme broke down the substrate.
Study Questions 5. In the temperature simulation what was the optimal temperature? What explains the reduced rate of reaction at temperatures above the optimal? What about temperatures below the optimal? 6. Explain why your results of the optimal temperature of the lactase enzyme make sense for the human enzyme.
Set the sample size to 10. Leave the lactase enzyme concentration set at 5 mM for this and all of your experiments. Run the simulation at initial lactose (the substrate) concentrations of 10, 20, 40, 60, 80, 100, and 120 millimoles (mM). After each simulation at each concentration, click on the "mean of samples" tab.

In this laboratory, you will study some of the basic principles of molecular movement in solution and perform a series of activities to investigate these processes.
Promoter: This is a site for regulation of transcription. Every structural gene in eukaryotes has the promoter site which consists of several hundred nucleotide sequences that serve as the recognition point for RNA polymerase binding, located at a fixed distance from the site where transcription is initiated.
The results of this experiment reveal that amylase requires a specific temperature in order to function properly. Temperature is an important factor in determining how an enzyme functions. When the temperature of an enzyme changes, so does the 3D structure of the enzyme. The 3D structure is crucial for the enzyme's ability to act as a catalyst.

Oct 31, 2011 · The name 'nylonase' is a little misleading, since it's not nylon that the enzyme degrades, but a by-product of nylon-6 production. The enzyme's actual name is 6-aminohexanoate-dimer hydrolase. While the by-product also isn't found in nature, the bonds that hold it together (amide bonds) are nothing unusual, so it's not as impressive as "nylon ...

Enzyme Inhibitors reduce the rate of an enzyme catalysed reaction by interfering with the enzyme in some way. This effect may be permanent or temporary . Competitive Enzyme Inhibitors work by preventing the formation of Enzyme-Substrate Complexes because they have a similar shape to the substrate molecule.

we will use one of these commercial products, lactaid, as our source of lactase enzyme. Both the normal substrate of this enzyme (lactose) and the products (glucose and galactose) are colorless. However, lactase will also hydrolyze ONPG (Ortho-NitroPhenol-beta-Galactopyranoside) to ONP and galactose. ONPG is colorless, but ONP is bright yellow.

enzyme and then ligate the DNA insert into the vector with DNA Ligase. The insert contains a selectable marker which allows for identification of recombinant molecules. An antibiotic marker is often used so a host cell without a vector dies when exposed to a certain antibiotic, and the host with the vector will live because it is resistant. many of the dehydrogenase enzymes. Both NAD+ and NADH have strong UV absorbances, but at 340 nm, NADH has a much higher absorbance than NAD+. Therefore, the enzyme’s activity can be directly measured. A coupled reaction (Fig 1) uses one of the products as a reactant for an additional enzyme. That enzyme is typically easy to measure. The husband is a bit taken aback, and says, "Listen, I'm getting old. I can only "do that" about once a week." The doctor answers that he understands perfectly and gives the couple a vial, telling the husband to come back next week with a semen sample. The next week, the husband comes in with an empty vial. 1. No food or drink is allowed in lab unless food or drinks are provided as a part of the lab.
