Enzyme activity prelab quiz

What is the function of the active site of an enzyme?

• The active site is responsible for enzyme degradation.
• The active site is where enzymes are produced.
• The active site of an enzyme functions as the region where substrates bind and undergo a chemical reaction.
• The active site prevents substrates from binding.

What is the rate of reaction?

• The rate of reaction is the temperature at which a reaction occurs.
• The rate of reaction measures how quickly reactants are converted into products.
• The rate of reaction is the amount of energy released during a reaction.
• The rate of reaction is the total mass of reactants used in a reaction.

For our lab practice, the enzyme catalase is present in

The role of hydrogen peroxide in the lab practice is to be

• a catalyst

• a product

• a substrate

• an enzyme

The reaction in the lab practice will be

• Anabolic and endergonic

• Catabolic and endergonic

• Anabolic and exergonic

• Catabolic and exergonic

What is the activation energy?

• The activation energy is the energy required to break chemical bonds.
• The activation energy is the minimum energy needed for a reaction to proceed.
• The activation energy is the energy released during a reaction.
• The activation energy is the total energy of the reactants.

What is the role of the substrate concentration in a reaction?

• Substrate concentration influences the reaction rate, increasing it until saturation is reached.
• Substrate concentration only affects the temperature of the reaction.
• Higher substrate concentration always increases the reaction rate.

• Substrate concentration has no effect on reaction rate.
