Describe the relationship between substrate concentration and the early reaction price of an enzyme-catalyzed reaction. Is this a linear relationship? What wake up to the initial reaction price as substrate concentration increases?

Answer: Yes, the partnership is linear. The early reaction rate increases as the substrate concentration increases. With an ext substrates, there will certainly be a an ext of the reaction occurring until saturation began in 4 g, after ~ this concentration the reaction price is steady( in every pH) as mention in graph and also table.

You are watching: What is the maximum initial reaction rate for the lactase enzyme at ph 7?

What is the best initial reaction price for the lactase enzyme at pH 7?

Answer: 350

Explain why the best initial reaction rate cannot be reached at short lactose concentrations.

Answer: over there is not enough substrate for it to with the maximun initial rate.The maximun early reaction rate is350 (x10^6) molecules of product and also there are sufficient substrates accessible to produce that plenty of products.

What does your data indicate around the optimum pH level for this lactase-catalyzed reaction?

Answer: The day indicates the the greatest enzyme task is in pH the 7. Saturation began in 4 g, after ~ this concentration the reaction price is stable (in all pH) as mention in graph and also table.

Enzymes role most efficiently at the temperature that a typical cell, i beg your pardon is 37 degrees Celsius. Increases or to reduce in temperature can considerably lower the reaction rate. What walk this suggest about the importance of temperature-regulating mechanisms in organisms? Explain.

Answer: This mechanism is pertained to the homeostasis and the temperature regulation. Also, enzymes have perfect temperature the they function at. Molecules relocating at high temperatures (more energy), and reactions are more likely come occur. As soon as temperature increases, it’s much more likely for reactions to occur. However, protein can become denature when temperature are too high. If the temperature to be to be boosted or lessened in the enzymes an ar from this optimal temperature, climate the enzymes efficiency to catalyze reactions would certainly decrease. As enzymes duty are essential for organisms, the organisms have failure in their tasks and possibly death in enzymatic dysfunction. So, temperature is really important in regulation mechanisms in organisms.

People through a lactose intolerance are able come take commodities such as Lactaid that contain the lactase enzyme with their meals. These products can it is in taken in pill form. Considering the fact that the pill type of the enzyme would need to travel through the person’s stomach, what special factor to consider would the producer the this product need to be pertained to about?Answer: Lactase enzyme works in non-acidic environment; the duodenum (the small intestine). So, when we need the lactase enzyme, it have to be activated in the tiny intestine and also the pill does not open in the stomach. We deserve to use part micro-coated pill to prevent the impact of stomach acid on the enzyme and also release the enzyme in the stomach (pills). Also, there space different commodities which use in patients who experienced lactase deficiency save lactase such as Lactase chewable tablets, Lactacid, Lacteeze. In addition, probiotics deserve to use in this disorder. Yogurt and also other typical starter cultures and probiotic bacteria in fermented and unfermented milk products improve lactose digestion and also eliminate symptoms of intolerance in lactose mal-digesters. These valuable effects are because of microbial β-galactosidase in the (fermented) milk product, delay gastrointestinal transit, positive effects on minister functions and colonic microflora, and reduced sensitivity come symptoms. Undamaged bacterial cabinet walls, which act as a mechanical protection of lactase throughout gastric transit, and the relax of the enzyme into the little intestine are factors of efficiency. Lactobacillus acidophilus supplementation may help in breaking under lactose and used in this disorder.
