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 is the true relationship between pH and enzyme action?
The enzyme has an optimal point of pH at which the enzyme works best. For example a catalase enzyme works best in a pH of 7. When the pH changes it denatures the enzyme causing it to not be able to react with the substrate.
Four ways hormones may alter cellular activity?
1) Change in membrane permeability and/or voltage 2) Enzyme activation/inactivation 3) Initiation of secretory activity 4) Synthesis of regulatory molecules such as enzymes
Which enzyme shows the greatest change in its rate of action with the least change in pH?
The enzyme pepsin shows the greatest change in its rate of action with the least change in pH. Pepsin works optimally at a highly acidic pH of around 2, and even small changes in pH can significantly impact its activity.
How does heat denature enzymes?
Many things can denature proteins. Proteins have different optimal ranges in pH and temperature and outside of these optima then the enzyme will not work as well or at all. Also specific detergents will denature an enzyme depending on the enzyme.
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.

What are some factors that may influence enzyme activity?
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.

4 Stimuli that regulate gastrointestinal tract activity are generated by what?
Stimuli that regulate gastrointestinal tract activity are generated by factors such as nervous system inputs, mechanical stretch of the intestinal wall, chemical stimuli from food and hormones released by the digestive organs. These stimuli play a crucial role in coordinating digestion and absorption processes in the gastrointestinal tract.
What is the optional pH that this enzyme functions at?
The optimal pH for an enzyme's activity varies depending on the specific enzyme in question. Generally, most enzymes function best at a pH close to neutral (around pH 7), while others may have optimal activity in more acidic (pH 4-6) or alkaline (pH 8-10) conditions. For accurate information, it's essential to refer to the specific enzyme's characteristics or experimental data.

What is the 4 step process of an enzyme at work?
Substrate binding: The enzyme binds to its substrate. Catalysis: The enzyme facilitates the conversion of the substrate into product. Product release: The enzyme releases the product of the reaction. Enzyme recycling: The enzyme returns to its original state to catalyze further reactions.
Which enzyme shows the greatest change in its rate of action with the least change in pH?
The enzyme pepsin shows the greatest change in its rate of action with the least change in pH. Pepsin works optimally at a highly acidic pH of around 2, and even small changes in pH can significantly impact its activity.
What temperature is the best for enzyme solution storage?
Enzyme solutions are typically stored at a temperature between 4-8 degrees Celsius to maintain their stability and activity. This range helps slow down enzyme denaturation and minimize degradation, ensuring that the enzyme remains effective for a longer period. It's important to check the specific storage recommendations for the particular enzyme being used, as optimal conditions can vary.
Which curve was most likely generated from analysis of an enzyme from a human stomach where conditions are strongly acid?
The curve most likely follows a pH profile where the enzyme shows maximum activity at very low pH values (strongly acidic conditions). This would suggest that the enzyme is optimized to function efficiently in the acidic environment of the human stomach.
What are 5 lifestyle factors that promote good health?
