Extreme temperatures can alter an enzymes shape therefore the specific molecule might not be able to "fit" into that enzyme.
Enzymes are proteins that catalyze reactions in biological systems. They are typically complex and "flexible". As molecules, their bonds are subject to excitation. At low temperatures, do not flex enough to let in the substrate. Also, the substrates and enzymes do not move around (brownium motion).However, as temperature increases so does the vibration of the molecules and the chance that the enzyme is "denatured" or broken and in need of repair. So reaction rate increases with temperature until a maximum is met. After the optimum temperature is reached, the denaturing effect of temperature is greater than its effect on reaction rate. This is why the graph shows a gradual increase until the optimum where it suddenly drops off.

What conditions can be drawn about the action of the enzymes as the temperature increases?
As temperature increases, enzyme activity generally increases up to a certain point (optimal temperature) where the enzyme works most efficiently. Beyond the optimal temperature, the enzyme's activity rapidly declines due to denaturation. Extreme temperatures can disrupt the enzyme's active site, altering its shape and preventing it from catalyzing reactions effectively.
Some factors that may influence enzyme activity?
A low temperature can slow down enzyme activity and high temperatures can denature an enzyme making it unusable. pH levels also affect enzyme activity. Every cell has an ideal temperature and pH
What happens to the activity of an enzyme on either side of its temperature optimum?
Lower temperature: The energy input increases the flexibility of bonds in proteins. Higher temperature: Too much energy makes the bonds between the proteins brake and the protein unfolds 'denatures'
What conclusion can be drawn about the action of the enzymes as the temperature increase?
enzyme A becomes less effective earlier than enzyme B enzyme b stays effective at higher temperatures than enzyme a
3 factors that influence enzyme activity?
The three main factors that affect enjyme activity are:- a)Temperature:Enzymes generally function properly at a narrow rangr of temperature and shows its highest activity t a particular temperature called its optimum temperature. b)pH:-as temperature pH also has a particular value ,in which the enzymes are most active,called the optimum temperature. c)Concentration of substrate;-with the increase in substrate concentration,the velocity of the enzymatic reaction also increases,till a maximum velocitywhich does not rise any further with the rise in substrate concentration.

What accurately describes how temperature affects enzyme activity?
Temperature can affect enzyme activity by either increasing or decreasing the rate of the reaction. Low temperatures can slow down enzyme activity, while high temperatures can denature enzymes, leading to a loss of function. Each enzyme has an optimal temperature at which it functions most efficiently.

What happens to the rate of the enzyme as the temperature increases from 0c to 30c?
As the temperature increases from 0°C to 30°C, the rate of the enzyme activity generally increases due to enhanced molecular movement and more frequent collisions between enzymes and substrates. However, this increase continues only up to a certain optimal temperature, beyond which the enzyme may start to denature and lose its activity. Therefore, while the rate rises with temperature initially, it can decline if the temperature exceeds the enzyme's optimal range.
How does temperature affects activity?
The enzyme activity increases as the temperature rises due to the substrates colliding with the enzymes' active sites more frequently at higher temperatures. However, each enzyme has an optimum temperature as high temperatures denature enzymes.
What are the relationships between enzymes and temperature?
Enzymes are sensitive to changes in temperature. Increased temperature usually increases the rate of enzyme-catalyzed reactions up to an optimal point, beyond which the enzyme may become denatured and lose its activity. Low temperatures may slow down enzymatic activity, as enzymes require a certain level of kinetic energy to function efficiently.

enzyme A becomes less effective earlier than enzyme B enzyme b stays effective at higher temperatures than enzyme a

Explain how temperature pH and concentration affect enzyme activity?
Temperature, pH, and concentration significantly influence enzyme activity. Enzymes typically have an optimal temperature and pH range; deviations can lead to denaturation or reduced activity. Additionally, substrate concentration affects the rate of reaction—up to a point—where enzyme saturation occurs, beyond which increases in substrate do not enhance activity. Overall, maintaining optimal conditions is crucial for maximizing enzyme efficiency.
What is the effect of temperature on enzymes activity of lactose in bacterial cells?
Temperature significantly affects the activity of lactose enzymes in bacterial cells. Generally, as temperature increases, enzyme activity rises due to enhanced molecular movement, up to an optimal temperature where the enzyme functions best. Beyond this optimal point, high temperatures can lead to denaturation of the enzyme, causing a loss of activity. Therefore, maintaining an appropriate temperature is crucial for optimal lactose enzymatic activity in bacteria.
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.
