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 basic function of a coenzyme?
A coenzyme helps an enzyme do its' work. Without the coenzyme, the enzyme will remain inactive.
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 enzyme's optimum pH?
I believe it's 7.3, the pH of human blood, as most enzymatic reactions occur there. However, there are special enzymes, such as the ones which are in the stomach, which work best at around a pH of 2.
How does temperature and pH affect amylase activity and why?
Anylase works best in a slightly basic pH so a very acidic pH will denaturate the enzyme making it unable to do it's job.Effects of pHEnzymes are affected by changes in pH. The most favorable pH value - the point where the enzyme is most active - is known as the optimum pH.Extremely high or low pH values generally result in complete loss of activity for most enzymes. pH is also a factor in the stability of enzymes. As with activity, for each enzyme there is also a region of pH optimal stability.In addition to temperature and pH there are other factors, such as ionic strength, which can affect the enzymatic reaction. Each of these physical and chemical parameters must be considered and optimized in order for an enzymatic reaction to be accurate and reproducible.Hope this helps ;)
Cranial is the basic anatomical term for which of the following?

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.
The basic function of a coenzyme?
A coenzyme helps an enzyme do its' work. Without the coenzyme, the enzyme will remain inactive.
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.
What is the enzyme that works in both acidic and basic pH?

What are the functions of protease?
Protease is an enzyme that works to break down proteins into their basic amino acids. Specifically, it is any enzyme that performs proteolysis.

What effect does cooking have on enzyme activity?
You mean heating the enzymes? heating to a certain degree increases their rate of catalytic activity, until about 30-40 degrees Celsius. However if you continue heating, the enzyme's basic structure will be deformed (it changes shape), and since structure is essential to function, the enzymes activity will be reduced. that happens around 60-70 degrees Celsius, but it is different in various organisms.
What is the basic function of a coenzyme?
attaches to an enzyme and allows a chemical reaction to take place
