Enzymes Quiz

What are enzymes?

• Inorganic compounds

• Globular proteins

• Lipids

• Carbohydrates

What is the general naming convention for enzymes?

• Ending in -ose

• Ending in -ase

• Starting with enz-

• Starting with bio-

How do enzymes compare to laboratory or industrial catalysts?

• Less efficient and slower acting

• Equally efficient and fast acting

• More efficient and faster acting

• Unrelated in terms of efficiency and speed

Are enzymes specific to a particular biochemical reaction?

• Yes, each enzyme is unique to a specific reaction

• No, enzymes can catalyze multiple reactions

• Enzymes are not involved in biochemical reactions

• Enzymes are only involved in laboratory reactions

What is the effect of pH and temperature on enzyme activity?

• pH and temperature have no effect on enzyme activity

• Enzymes function over a wide range of pH and temperature

• Enzymes function over a narrow range of pH and temperature

• Enzymes function best at extreme pH and temperature

How can enzymes be denatured?

• By changes in pressure

• By changes in concentration

• By changes in pH or temperature

• By changes in light exposure

Which of the following is an example of an enzyme involved in hydrolysis?

• Amylase

• Succinate dehydrogenase

• Ascorbic acid oxidase

• Polymerase

What is the primary structure of an enzyme?

• Shape of the enzyme caused by hydrogen bonding

• Folding and bending of the enzyme molecule

• Sequence of amino acids making up the enzyme

• Interaction of alkyl (R) groups

Which model describes the interaction between enzymes and substrates?

• Lock and Key Model

• Induced Fit Model

• Both Lock and Key Model and Induced Fit Model

• Neither Lock and Key Model nor Induced Fit Model

What happens to enzyme activity at temperatures above the optimum?

• Activity increases

• Activity decreases

• Activity remains the same

• Enzyme becomes denatured
