Which of these is NOT true?

Enzymes can only be used once in a chemical reaction

Enzymes can denature (change shape) when the temperature gets too high

Enzymes can denature when the pH changes

Enzymes are proteins that help increase the rate of chemical reactions inside cells. These proteins are composed of many simpler molecules called amino acids. Which of the following suggests that the shape of an enzyme determines the enzyme’s function?

Enzymes are specific to a substrate

Enzymes can operate in a wide range of conditions

Enzymes are activated by neighboring molecules

Enzymes can be found in all life-forms

Which enzyme is most efficient in a basic (alkaline) solution?

neither are efficient in a basic solution

Increasing substrate concentration increases the rate of reaction. This is because....

more substrate molecules will be colliding with enzyme molecules, so more product will be formed

less substrate molecules will be colliding with enzyme molecules, so less product will be formed

the temperature will increase, resulting in faster reactions

the rate of denaturation of enzymes will decrease

At high temperatures enzyme activity declines because of....

dissociation of ionic compounds

The enzyme known as ‘catalase’ is involved in the breakdown of hydrogen peroxide molecules into separate water and oxygen molecules. During this reaction, what happens to the ‘catalase’?

the enzyme would remain unchanged in any way

the enzyme would become products: O 2 and H 2 O

the enzyme would be fully used up and discarded

the enzyme would become a new type of enzyme

By what chemical process are enzymes synthesized?

polymerization of carbohydrates

condensation reaction between fatty acids and glycerol
