enzyme require an optimum temperature and ph level to be active. temperature at which most enzymes are active is around 35-40 degree celcius. above this temperature the enzyme loses it globular structure and thus the substrate will not be able to bind with it.
some enzymes are active in alkali ph while others are active in acidic temperature. but most of the enzymes are active in neutral ph and this helps to maintain its globular structure.
What else can I help you with?
What are reactants that enter enzyme-controlled reactions?
Reactants that enter enzyme-controlled reactions are typically substrates. Substrates are the specific molecules that enzymes act upon to catalyze a biochemical reaction. The enzyme binds to the substrate at the enzyme's active site, where the reaction takes place.
What is the effect of excess heat or temperature on an enzyme-?
With a lot of heat, the enzyme will be denatured meaning it will lose its shape and therefore its function.
What factors in a cell can speed up or slow down enzyme reactions?
Factors that can speed up enzyme reactions include higher enzyme or substrate concentrations, optimal pH and temperature, and the presence of cofactors or coenzymes. Factors that can slow down enzyme reactions include low substrate concentrations, extremes in pH or temperature, and the presence of inhibitors.
How could you determine the correct temperature range and salt concentration and pH for a specific enzyme?
Do a controlled experiment in which you get an enzyme and set them up in different temperature, salt concentration and pH levels and see which reacts the best.
What must be held constant when testing the effect enzyme concentration on enzyme activity?
temperature,pH and substrate concentration
What is a question your trying to answer in a lab?
One question that a lab might be trying to answer is: What is the effect of temperature on enzyme activity? This type of experiment would involve testing how changes in temperature impact the rate of enzyme-catalyzed reactions in a controlled setting.
Why is the optimum temperature for many enzymes controlled reactions about 40 degrees of centigrade?
The optimum temperature for many enzymes is around 40 degrees Celsius because that is the temperature at which the enzyme's activity is highest. At this temperature, the enzyme's structure is optimal for binding to substrates and catalyzing reactions efficiently. Temperatures above or below this optimum can cause denaturation of the enzyme, leading to a loss of activity.
Which graphs likely represents the effect of temperature on photosynthetic reactions?
An exponential graph is likely to represent the effect of temperature on photosynthetic reactions, as the rate of photosynthesis typically increases with temperature up to a certain point before leveling off or decreasing due to enzyme denaturation. The initial increase is due to higher kinetic energy and enzyme activity, while the decrease is a result of enzyme inactivation.
What factors increase the rates of enzyme-controlled reactions?
Factors that can increase the rates of enzyme-controlled reactions include higher substrate concentration, optimal pH and temperature conditions, the presence of cofactors or coenzymes, and specific enzyme activators. Additionally, enzyme concentration and the absence of competitive inhibitors can also enhance reaction rates.
What is the effect of excess heat or temperature on enzyme?
Each enzyme has its ideal temperature
What are reactants that enter enzyme-controlled reactions?
Reactants that enter enzyme-controlled reactions are typically substrates. Substrates are the specific molecules that enzymes act upon to catalyze a biochemical reaction. The enzyme binds to the substrate at the enzyme's active site, where the reaction takes place.
What is a special protein that effect the rate of chemical reactions?
An enzyme
What is the series of enzyme-controlled reactions that build complex material from simple material?
Anabolism
What can effect the shape of an enzyme molecule?
Temperature
What kind of chemical reactions speed up enzyme catalysis?
This varies per enzyme and what it catalyzes but chemical reactions that result in an increase in temperature often speed up enzyme catalysis.
Why above a certain temperature enzyme-catalysed reactions actually go more slowly if the temperature is raised?
because the enzyme is becoming denatured
What is the effect of excess heat or temperature on an?
Each enzyme has its ideal temperature
