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?
Answer: 350Explain 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.
