Which of the following is not one of the three basic steps involved in enzyme activity?
"Because their catalytic role renders most enzymes ineffective after their initial activity, a cell must produce large amounts of each enzyme in order to perform effectively."
this is incorrect because 99+% of enymes are used until the cells dies because they are costly (in energy terms) to make.

The activity of which enzyme decreases in both acidic and basic envioroment?
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.
What will most likely happen to an enzyme if it is placed in an environment that is too acidic or too basic?
If an enzyme is placed in an environment that is too acidic or too basic, its structure can be denatured, which means its active site will change shape and it will no longer be able to catalyze reactions effectively. This will decrease or even stop its enzymatic activity.
The basic function of a coenzyme?
Coenzymes assist enzymes in catalyzing biochemical reactions by transfering chemical groups or electrons from one molecule to another. They act as cofactors that are essential for enzyme activity, often participating in the reaction itself and helping the enzyme function properly.
What are some easy enzyme lab experiments that can be conducted in a classroom setting?
Some easy enzyme lab experiments that can be conducted in a classroom setting include testing the effect of temperature on enzyme activity, investigating the impact of pH on enzyme function, and exploring the role of substrate concentration on enzyme reactions. These experiments can provide valuable insights into how enzymes work and are commonly used in educational settings to demonstrate basic enzymatic principles.
How does pH affect enzyme activity Use the enzymes pepsin and trypsin as examples?
Enzymes work within a range of pH levels. Pepsin, which is found in the stomach works in an acidic environment, while trypsin functions in a basic surrounding in the intestines. Increasing or decreasing the pH levels can stop the activity of these enzymes.

What is the effect of pH upon the relative enzyme activity?
Different enzymes work best at different pH. This is refered to as the ideal pH for the enzyme. For example, the digestive enzyme trypsin works best at an acidic pH while alkaline phosphatase works best at a basic pH. Therefore, enzyme activity varies with pH and this variation depends on the enzyme being studied
What are the principles involved in inversion of sucrose?
The principles that are involved in inversion of sucrose are the basic mechanisms for enzyme catalyzed reactions. These mechanisms were first proposed by Michaelis and Menten in 1913.

What effect do acidic and basic solutions have on enzyme moleculues?
pH - denatures the enzyme by altering the charges on the enzyme. This will affect the structure of the enzyme and its ability to function. Heat - will denature the enzyme by breaking its bonds. This will stop the enzyme from being able to bond to a specific substrate molecule. Cold - not enough energy to reach minimum amount of activation energy needed to undergo reaction. The enzyme will not be able to react on the substrate.
Is blood considered neutral on PH scale?
No, blood is slightly basic with a pH around 7.35-7.45. This pH range is necessary for the body to maintain proper functioning and support enzyme activity.
If a base is added gradually to a solution with a pH of 6 containing enzyme C and its substrate the rate of action of enzyme C would most likely?
Increase initially due to the pH shift towards the optimum pH range for enzyme C, then decrease as the pH becomes too basic and denatures the enzyme. Enzymes have an optimal pH at which they function most efficiently, and deviations from this pH can impact their activity.
How the organic solvents inhibit enzyme activity?
The organic solvents are either acidic or basic and capable of producing protons and ions. These protons and ions changes the pH of the solution in which they are present. Once the pH is changed the amino acids cannot retain its original form. They tend to form either cation or anion which inturn alters the normal structure of the protein (enzyme) and hence the activity is also inhibited.
