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.
A good enzyme lab for IB Biology could involve investigating how factors such as temperature, substrate concentration, or pH affect the activity of an enzyme like amylase. Students could test the enzyme activity under different conditions using a spectrophotometer to measure changes in absorbance, or by observing changes in the rate of a reaction such as the breakdown of starch. This type of lab allows students to explore enzyme kinetics and understand the factors that influence enzyme activity.
Denaturation caused by high temperatures or extreme pH levels can change the shape of an enzyme, disrupting its active site and preventing it from binding to its substrate effectively. Additionally, the presence of inhibitors or competitive molecules can also alter the enzyme's shape, leading to a reduction or loss of enzyme activity.
Pepsin secreted in the stomach, works at highly acidic pH and the pH could be as low as 2. The optimal pH for pepsin is thus near about 2. This pH is maintained by HCl secreted by the gastric glands in the stomach.

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.
Factors affecting enzyme activity1: Enzyme concentrationIf the quantity of enzyme is doubled, the enzymatic activity will also be doubled because more enzymes are now available to work. After a certain level of enzyme concentration, there will be no more increase in the enzymatic activity because all the substrate molecules are combined with an enzyme and the rate of reaction will stabilize.2: Substrate concentrationBy increasing substrate concentration, enzymatic activity increases. Increasing the substrate further without increasing the enzyme concentration will not affect the enzymatic activity because all the enzymes are occupied by a substrate molecule.3: pH valueSome enzymes require acidic surroundings, most require a more neutral condition for their activity. Change in the pH can change the enzyme's structure and enzyme become useless.4: TemperatureAn increase in temperature of 10 degree celsius doubles the enzymatic activity. Each enzyme has its own optimum temperature at which its enzymatic activity is maximum. Very high temperatures break the bonds that maintain shape of enzyme. If the enzyme denatures, the substrate can not fit in to the active sites and enzyme become useless.
We tested the effect of different temperatures on enzyme activity in Setup 1 and the effect of varying pH levels on enzyme activity in Setup 2.
pH and Temperature both impact the enzyme's function.What_factors_affect_enzyme_production
Two biological variables that affect how well an enzyme functions in the body are temperature and pH. Enzymes have optimal temperature and pH ranges at which they function most efficiently, deviation from these ranges can lead to denaturation and loss of enzymatic activity.

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.
The enzyme whose activity decreases in both acidic and basic environments is pepsin. Pepsin is an enzyme found in the stomach that functions optimally at a pH of around 2. In environments that are either too acidic or too basic, the structure of pepsin can be denatured, leading to a decrease in enzymatic activity.
Denaturation caused by high temperatures or extreme pH levels can change the shape of an enzyme, disrupting its active site and preventing it from binding to its substrate effectively. Additionally, the presence of inhibitors or competitive molecules can also alter the enzyme's shape, leading to a reduction or loss of enzyme activity.
The optimum temperature for an enzyme is the temperature at which it exhibits maximum activity. For enzyme 2, its optimum temperature would be specific to that enzyme and can vary depending on its source. Usually, it falls within the range of 37-40°C for most enzymes found in human cells.
