The way enzymes work is by providing a bonding site at which various compounds (substrates) can come in contact and easily react with each other through some mechanism. If the temperature of the system is increased slightly, the substrates will have more energy and will thus collide more frequently, allowing for more reactions. However, if the temperature increases significantly, such as to the boiling point of water, they become extremely deformed, and since their function was dependent on their shape, this cripples their ability to catalyze reactions. While a few bonding sites may still be active, many will not, and those that are will have lost some of their functionality due to the change in shape
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 effect do temperature and pH have on enzyme controlled reactions?
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 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 is a enzyme controlled reaction?
An enzyme-controlled reaction is a biochemical process in which an enzyme acts as a catalyst to accelerate the rate of a chemical reaction without being consumed in the process. Enzymes lower the activation energy required for the reaction to occur, allowing substrates to convert into products more efficiently. These reactions are highly specific, meaning that each enzyme typically catalyzes only one type of reaction or acts on a specific substrate. Enzyme activity can be influenced by factors such as temperature, pH, and the concentration of substrates or inhibitors.
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.
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.
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 series of enzyme-controlled reactions that build complex material from simple material?
Anabolism
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
WHich action would most likely increase the rate of an enzyme-controlled reaction during an experiment?
Increasing the temperature or increasing the concentration of substrate would most likely increase the rate of an enzyme-controlled reaction during an experiment. This is because higher temperatures or substrate concentrations can speed up the rate of enzyme-substrate collisions, leading to more enzymatic reactions taking place.
Is temperature a factor that affects enzyme activity?
Yes, temperature is a critical factor that affects enzyme activity. Generally, enzymes work within an optimal temperature range, beyond which they can become denatured and lose their function. Changes in temperature can alter the rate of enzyme-catalyzed reactions.
Is temperature important to enzyme reactions?
Yes because if the heat is to hot it can damage the enzymes
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.
