What factors affect enzyme activity?
Temperature - too cold the enzyme will still work but slowly, too hot and the enzyme will become denatured . As temperature increases, the kinetic energy of the molecules increases so they move around more, meaning that there are more collisions between the enzymes and substrate molecules and therefore more reactions. pH - different types of enzymes work best in different pH environments. A change in pH interferes with the shape of the enzymes active site (where it bonds and reacts with substrate) and therefore does not fit the shape of the substrate as well so the enzyme is unable to work on the substrate. enzyme and substrate concentration - how many there is of each. Changing the concentrations of enzyme and substrate concentrations will affect the number of collisions between them and therefore the number of reactions. enzyme inhibitors - these are molecules which bind to enzymes, reducing their activity (many drugs are enzyme inhibitors). co-factors - these are chemical compounds which bind to enzymes and which are needed by the enzyme to work on substrate molecules. They are often called helper molecules.
What determines the effectiveness of enzymes?
The effectiveness of enzymes is determined by factors such as temperature, pH, substrate concentration, and enzyme concentration. Enzymes work optimally within a specific range of these factors and can become less effective or denatured if conditions stray too far from the ideal range. Additionally, the specificity of an enzyme for its substrate also plays a key role in its effectiveness.
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
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 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.
The graph below shows how two different enzymes react with a substrate as the temperature increases. Based on the results what conclusion can be drawn about the action of the enzymes as the temperatur?
enzyme B stays effective at higher temperatures than enzymes A
How do pH temperature and substrate availability affect the rate of action of enzymes?
All enzymes have optimal conditons, when it will work at its best. For example, if the temprature is too high the protein can become denatured. This is alos the case with Ph. Substrate level also affects enzyma activity because the more substartes there are, the more enxymes can bind to them.

What effect enzymes activity?
Temperature, pH, substrate concentration
How can enzymes be inactived?
All enzymes work best at a certain temperature and pH. They also need a substrate to work on. A change in pH or temperature will inactive it by denaturing it. If the substrate is very low in quantity or is absent, the enzyme will be inactive.
What factors that will affect enzymes speed?
Factors that affect enzyme speed include temperature, pH, substrate concentration, and the presence of inhibitors or activators. Enzymes work best within a specific temperature and pH range, and their activity increases with higher substrate concentration until reaching saturation. Inhibitors can slow down enzyme activity, while activators can enhance it.

What changes are enzymes sensitive to?
Enzymes are sensitive to changes in temperature, pH levels, and substrate concentration. These factors can affect the enzyme's shape and ability to function effectively.
The graph below shows how two different enzymes react with a substrate as the temperature increases. Based on the results what conclusion can be drawn about the action of the enzymes as?
Based on the graph, it can be concluded that one enzyme is more temperature-sensitive than the other. This is evident by the steeper slope of one enzyme's curve, indicating a faster increase in activity with temperature. Additionally, both enzymes exhibit an optimum temperature where their activity is highest before declining due to denaturation.

Where does an enzymes join with a substrate?
The enzyme substrate complex
