The higher a temperature is, the faster things go. This is because molecules move faster at higher temperatures. The opposite is true for cold temperatures- molecules move slower, and so do the reactions. Temperature also has different effects on specific organisms-- for example, a hot spring bacterium has enzymes that generally work better in hotter temperatures.

What three factors affect the rate of a biochemical reaction?
The three factors that affect the rate of a biochemical reaction are temperature, substrate concentration, and enzyme concentration. Temperature influences the kinetic energy of molecules involved in the reaction, substrate concentration determines the amount of reactants available for the reaction, and enzyme concentration affects the number of catalysts available to facilitate the reaction.
Changes in pH or temperature decrease enzyme activity because bonds break and the enzyme returns to its tertiary structure?
Changes in pH or temperature can disrupt the interactions that maintain the enzyme's specific shape, leading to denaturation and loss of enzyme activity. This is because enzymes are sensitive to changes in their environment, and alterations in pH or temperature can affect the enzyme's active site conformation, preventing it from binding to the substrate effectively.
What most likely happens to the rate of reaction of a human enzyme when the temperature is increased gradually from 10 degrees Celsius to 30 degrees Celsius?
The rate of reaction of a human enzyme typically increases as the temperature rises from 10 to 30 degrees Celsius due to increased kinetic energy, leading to more collisions between enzyme and substrate molecules. However, beyond the optimum temperature range, denaturation may occur, causing a decrease in enzyme activity.
How does the presence of competitive inhibitors impact the maximum reaction rate (Vmax) of an enzyme?
Competitive inhibitors decrease the maximum reaction rate (Vmax) of an enzyme by competing with the substrate for the enzyme's active site, which reduces the efficiency of the enzyme-substrate complex formation and slows down the rate of the reaction.
How does temperature affect catalase?
Temperature affects catalase activity by increasing it up to an optimal point, after which activity begins to decrease due to denaturation of the enzyme. Higher temperatures generally lead to faster reaction rates up to the optimal temperature. Cooling below the optimal temperature can also slow down the reaction rate.
What are 3 factors that affect the speed of an enzyme catalyzed reaction?
3 factors that affect the speed of an enzyme catalysed reaction are: .Temperature .Enzyme Concentartion .Substrate concentration
What is the relationship between an enzyme temperature and the chemical reaction in which the enzyme is invoved?
Rate increase with temperature up to 40 celcius.But it decrease to 60 celcius and stops after.
The ability of an enzyme to catalyze a reaction is not affected by?
The ability of an enzyme to catalyze a reaction is not affected by changes in temperature or pH within a certain range known as the enzyme's optimal conditions. However, extreme changes in temperature, pH, or enzyme concentration can denature the enzyme and affect its activity. Additionally, the substrate concentration can affect the rate of reaction up to a point of saturation, where all enzyme active sites are occupied.
What three things can alter the rate of an enzyme?
Three things that can alter the rate of an enzyme are; temperature, pH and substrate concentration. Enzymes will have an optimal temperature and pH, at which they will have the greatest rate. Below or above these optimum conditions, the rate will be slower.
What three factors affect the rate of a biochemical reaction?
The three factors that affect the rate of a biochemical reaction are temperature, substrate concentration, and enzyme concentration. Temperature influences the kinetic energy of molecules involved in the reaction, substrate concentration determines the amount of reactants available for the reaction, and enzyme concentration affects the number of catalysts available to facilitate the reaction.
What are the four factors that effect enzyme activity?
The four factors that affect enzyme activity are temperature, pH, substrate concentration, and the presence of inhibitors or activators. Temperature and pH can alter the enzyme's shape, while substrate concentration determines the rate of reaction. Inhibitors and activators can either decrease or increase enzyme activity, respectively.
How does the non-competitive inhibitor decrease the rate of an enzyme reaction?
Noncompetitive inhibitors decrease the rate of an enzyme reaction by bonding to an enzyme somewhere other than the active site, deforming it and permanently disabling the enzyme, so that enzyme can never function again, so the rate of reaction decreases.
What would happen to an enzymes facilitated reaction if temperature were increased?
Increasing the temperature generally increases the rate of an enzyme-facilitated reaction up to an optimal point, as it enhances molecular movement and substrate collisions. However, if the temperature exceeds the enzyme's optimal range, the enzyme may denature, losing its three-dimensional structure and, consequently, its activity. This denaturation leads to a significant decrease or complete loss of the reaction rate. Therefore, while moderate temperature increases can enhance reaction rates, excessive heat can be detrimental to enzyme function.
What factors affect the rate of enzyme activity?
Factors that affect the rate of enzyme activity include temperature, pH, substrate concentration, and enzyme concentration. Temperature and pH can alter the shape of the enzyme, affecting its ability to bind to the substrate. Changes in substrate and enzyme concentration can affect the frequency of enzyme-substrate collisions, which impacts the rate of reaction.
As temperature decreases the rate of an enzyme-catalyzed reaction also decreases why?
Just like many other chemical reactions, the rate of an enzyme-catalyzed reaction will decrease with temperature because of the decrease in the number of high energy collisions between particles.
Changes in pH or temperature decrease enzyme activity because bonds break and the enzyme returns to its tertiary structure?
Changes in pH or temperature can disrupt the interactions that maintain the enzyme's specific shape, leading to denaturation and loss of enzyme activity. This is because enzymes are sensitive to changes in their environment, and alterations in pH or temperature can affect the enzyme's active site conformation, preventing it from binding to the substrate effectively.
What conditions affects the function of enzymes?
Conditions such as temperature, pH, substrate concentration, and enzyme concentration can affect the function of enzymes. High temperatures can denature enzymes, extremes in pH can alter their structure, low substrate concentration can slow down reaction rates, and low enzyme concentration can limit the rate of reaction.
