Concept explainers
(a)
Interpretation: The effect of increase in the concentration of hydrogen peroxide on the rate of the given biochemical reaction has to be predicted.
Concept introduction: If the concentration of an enzyme is kept constant and the concentration of a substrate is increased, then enzyme activity will also increase. The increase in the enzyme activity is up to a certain substrate concentration and thereafter it remains constant.
(b)
Interpretation: The effect of decrease in the temperature from its optimum value on the rate of the given biochemical reaction has to be predicted.
Concept introduction: The temperature at which an enzyme shows maximum activity is known as the optimum temperature.
(c)
Interpretation: The effect of decrease in the concentration of catalase on the rate of the given biochemical reaction has to be predicted.
Concept introduction: If the substrate concentration is kept constant, then the rate of an enzyme-catalyzed reaction will increase with an increase in the concentration of enzyme.
(d)
Interpretation: The effect of increase in the
Concept introduction: Most of the enzymes exhibit a narrow maximum activity over a narrow

- Describe the difference between graphs showing temperature versus reaction rate for an enzyme-catalyzed reaction and an uncatalyzed reaction.arrow_forwardWhat is the general role of enzymes in the human body?arrow_forwardThe site on an enzyme molecule that does the catalytic work is called the: a. binding site. b. allosteric site. c. lock. d. active site.arrow_forward
- Why are enzymes that are used for laboratory or clinical work stored in refrigerators?arrow_forward4. How are enzymes able to act as such remarkable catalysts of chemical reactions? Use a reaction coordinate diagram in your answer!arrow_forward13. A specific enzyme will usually only catalyze one particular reacton. True Falsearrow_forward
- Explain how enzymes catalyze reactions.arrow_forwardthe conversion of the amino acid phenylalanine into non-harmful tyrosine is mutated and doesn't work as well (or at all). Phenylalanine will still break down into tyrosine by itself, ol because this is a favorable reaction. Why is the non-functional enzyme a problem? Explain in a few sentences. 3.
